NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of Advanced Analogic Technologies Incorporated (the “Company”) have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted in accordance with these rules and regulations. The information in this report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in its Registration Statement on Form 10-K filed with the SEC on March 8, 2007.

In the opinion of management, the accompanying unaudited consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to summarize fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. The operating results for the three and six months ended June 30, 2007 are not necessarily indicative of the results that may be expected for the year ending December 31, 2007 or for any other future period. The consolidated balance sheet as of December 31, 2006 is derived from the audited consolidated financial statements as of and for the year then ended.

Cash and Cash Equivalents

Cash equivalents are highly liquid investments purchased with original maturities of 90 days or less at the time of purchase. Investments with maturities of over 90 days at the time of purchase are classified as short-term investments.

Investments

The Company accounts for its investment instruments in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 115, “Accounting for Certain Investments in Debt and Equity Securities” (“SFAS 115”). At June 30, 2007, the Company had investments in short-term debt instruments which were classified as available-for-sale under SFAS 115. Short-term investments consist primarily of high grade debt securities with a maturity of greater than 90 days when purchased. The Company classifies investments with maturities greater than one year as short-term investments as it considers all investments a potential source of operating cash regardless of maturity date. The Company’s debt securities are carried at fair market value with the related unrealized gains and losses included in accumulated other comprehensive loss, which is a separate component of stockholders’ equity. The cost of securities sold is based on specific identification method. Interest earned on securities is included in “Interest income” in the Condensed Consolidated Statements of Operations. The fair value of investments is determined using quoted market prices for those securities.

In addition to debt securities, a portion of the Company’s investment portfolio consists of an equity investment in a non-publicly traded company. The Company has classified this investment as long-term other assets. This investment is carried at cost and evaluated for other than temporary impairment at each reporting period. As of June 30, 2007, the Company did not recognize any other than temporary impairment on this investment.

2. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

FIN 48

On July 13, 2006, the Financial Accounting Standard Board (“FASB”) issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes—An Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes” and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a tax return. Under FIN 48, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, FIN 48 provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006.

6

The Company adopted the provisions of FIN 48 on January 1, 2007. The total amount of unrecognized tax benefits as of the date of adoption was approximately $2,417,000. If such unrecognized tax benefits are recognized, the effective tax rate would be affected. As a result of the implementation of FIN 48, the Company recognized approximately $550,000 of a net decrease in the liability for unrecognized tax benefits which was accounted for as follows:

Increase in Retained Earnings (cumulative effect)	$	848,000
Decrease in Retained Earnings (cumulative effect)	$	(305,000	)
Reduction in Deferred Tax Assets	$	7,000
Decrease in Liability	$	550,000

During the three and six months ended June 30, 2007, the Company increased its total amount of unrecognized tax benefits to approximately $2,579,000, including an accrual of interest and penalties of approximately $22,000. The Company recognizes interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the year ended December 31, 2006, the Company recognized approximately $16,000 in penalties and interest. During the years ended December 31, 2005 and 2004, no penalties and interest were recognized. There had been no payment of interest and penalties accrued at December 31, 2006. Upon adoption of FIN 48 on January 1, 2007, the Company increased its accrual for interest and penalties to approximately $95,000. During the three and six months ended June 30, 2007, the Company increased its accrual for interest and penalties to approximately $117,000.

The Company is subject to taxation in the United States and various states and foreign jurisdictions. The Company’s tax years for 1997 through 2006 are subject to examination by the tax authorities. Currently, an estimate of the range of the reasonably possible change in unrecognized tax benefits in the next 12 months cannot be made. The Company is no longer subject to foreign examinations by tax authorities for years before 2001.

SFAS 159

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 applies to all entities and is effective for fiscal years beginning after November 15, 2007. The Company does not believe SFAS 159 will have a material impact on its financial statements.

3. STOCK-BASED COMPENSATION

On January 1, 2006, the Company adopted SFAS No. 123 (revised 2004), “Share-Based Payment,” (“SFAS 123(R)”), which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees and directors including employee stock options and employee stock purchases related to the Employee Stock Purchase Plan based on estimated fair values.

The following table summarizes stock-based compensation expense related to employee stock options under SFAS 123(R), including the amortization of the intrinsic value under Accounting Principles Board Opinion 25, “Accounting for Stock Issued to Employees,” for pre-April 4, 2005 options, for the three and six months ended June 30, 2007 and June 30, 2006, which was allocated as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
Income statement classifications	2007		2006		2007		2006
	(in thousands)
Cost of sales	$	66	$	59	$	131	$	146
Research and development		662		624		1,273		1,181
Sales, general and marketing		1,019		803		2,053		1,566
Total stock-based compensation expense	$	1,747	$	1,486	$	3,457	$	2,893

7

The related tax effect for stock-based compensation expense for the three and six months ended June 30, 2007 was approximately $401,000 and $777,000, respectively, and approximately $10,000 and $101,000 for the three and six months ended June 30, 2006, respectively. The related tax effect was determined using the applicable tax rates in jurisdictions to which this expense relates.

On January 17, 2007, the Company accepted for exchange from eligible employees (excluding directors and Section 16 officers), options to purchase an aggregate of approximately 1.3 million shares of the Company’s common stock, pursuant to a stock option exchange program (the “Exchange Offer”) under Section 16 of the Securities Exchange Act of 1934, giving them the right to tender outstanding stock options that were granted between August 4, 2005 and September 1, 2006 (the “Old Options”). The Old Options were cancelled as of January 17, 2007. The Company granted new options to purchase an equal number of shares of its common stock with an exercise price at fair market value of $5.80 in exchange for the options cancelled in connection with the offer. These new options vest at the rate of 25 percent after one year starting from January 17, 2007 and 6.25 percent every three months thereafter. The Company calculated incremental compensation costs related to the Exchange Offer as required by SFAS 123(R), which together with the unamortized costs related to the Old Options, will be amortized over the vesting period of the new options.

For options granted subsequent to January 1, 2006, including the new options granted as a result of the Exchange Offer, the Company estimated expected volatility for options granted relying on a combination of historical and market-based implied volatility in accordance with guidance in SFAS 123(R) and Staff Accounting Bulletin No. 107. The Company determined that a combination of implied volatility and historical volatility is more reflective of market conditions and a better indicator of expected volatility than using purely historical volatility. The expected term of employee stock options represents the weighted-average period that the stock options are expected to remain outstanding. The Company derived the expected term assumption based on the Company and its peer group’s weighted average vesting period combined with the post-vesting holding period. The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected term of the Company’s employee stock options. The dividend yield assumption is based on the Company’s history and expectation of dividend payouts. The Company has never declared or paid any cash dividends on common stock, and it does not anticipate paying any cash dividends in the foreseeable future.

The following table includes the weighted average assumptions utilized for purposes of calculating the valuation of the Company’s stock option grants for the three and six months ended June 30, 2007 and June 30, 2006:

	Three Months Ended June 30,				Six Months Ended June 30,
	2007		2006		2007		2006
Volatility	48	%	59	%	49	%	57	%
Expected option term	4.07		6.25		4.17		6.25
Expected dividend yield	0	%	0	%	0	%	0	%
Risk free interest rate	5.10	%	4.98	%	4.80	%	4.74	%

4. NET INCOME (LOSS) PER SHARE

The Company calculates net income (loss) per share in accordance with SFAS No. 128, “Earnings Per Share” (“SFAS 128”). Under SFAS 128, basic net income (loss) per common share is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding during the reporting period excluding shares subject to repurchase. Diluted net income per common share reflects the effects of potentially dilutive securities, which consist of common stock options and warrants outstanding and restricted common stock subject to repurchase, using the treasury stock method. Basic and diluted net loss per share are the same for the three and six months ended June 30, 2007 due to the Company’s incurring losses for those periods. Approximately two million shares of dilutive potential common shares were excluded from the net loss per share calculation, as their inclusion would have been antidilutive.

A reconciliation of shares used in the calculation of basic and diluted net income (loss) per share is as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
	2007		2006		2007		2006
	(in thousands)
Weighted average common shares outstanding	44,678		43,773		44,537		43,589
Weighted average shares subject to repurchase	(76	)	(409	)	(76	)	(409	)
Shares used to calculate basic net income (loss) per share	44,602		43,364		44,461		43,180
Effect of dilutive securities:
Common stock warrants	—		41		—		45
Common stock options	—		3,004		—		3,268
Weighted average shares subject to repurchase	—		409		—		409
Dilutive potential common stock	—		3,454		—		3,722
Weighted average common shares outstanding, assuming dilution	44,602		46,818		44,461		46,902

5. OTHER COMPREHENSIVE INCOME (LOSS)

Comprehensive income (loss) includes charges or credits to equity that are not the result of transactions with owners. The components of comprehensive income (loss), net of taxes, are as follows:

	Three Months Ended June 30,						Six Months Ended June 30,
	2007			2006			2007			2006
	(in thousands)
Net income (loss)	$	(891	)	$	1,204		$	(3,642	)	$	1,950
Changes in cumulative translation adjustment		(12	)		(15	)		218			(15	)
Changes in unrealized gains /losses on investments, net of taxes		(20	)		4			(15	)		8
Total other comprehensive income (loss)	$	(923	)	$	1,193		$	(3,439	)	$	1,943

The changes in cumulative translation adjustment during the six months of 2007 included a write-off of $0.3 million cumulative translation adjustment loss as a result of the liquidation of the Company’s Sweden branch office.

9. INCOME TAXES

The Company recorded a tax provision of approximately $813,000 and $266,000 for the three months ended June 30, 2007 and 2006, respectively. Although the Company incurred a loss before income tax on a worldwide consolidated basis for the three and six months ended June 30, 2007, the Company remained taxable in certain jurisdictions where there were taxable profits. As a result, the Company recorded a tax provision for the three and six months ended June 30, 2007. For the six months ended June 30, 2007 and 2006, the Company recorded a tax provision of approximately $944,000 and $312,000, respectively. The Company accounts for income taxes under the provisions of SFAS No. 109, “Accounting for Income Taxes.” Under this method, the Company determines deferred tax assets and liabilities based upon the differences between the financial statement and tax bases of the Company’s assets and liabilities using tax rates in effect for the year in which the Company expects the differences to affect taxable income. The Company adopted SFAS 123(R) as of January 1, 2006, and, as a result, incurred significant stock-based compensation expense, including amounts related to incentive stock options for which no corresponding tax benefit is recognized unless a disqualifying disposition occurs. Disqualifying dispositions result in a reduction of income tax expense in the quarter when the disqualifying disposition occurs in an amount equal to the tax benefit relating to previously expensed stock compensation. During the three months ended June 30, 2007 and 2006, tax expense was reduced by approximately $16,000 and $10,000, respectively, as a result of disqualifying dispositions. During the six months ended June 30, 2007 and 2006, tax expense was reduced by approximately $37,000 and $101,000, respectively, as a result of disqualifying dispositions. As of June 30, 2007, the Company had not recorded tax benefits related to tax deductions in excess of previously expensed stock compensation because the Company has a net operating loss carry forward. Due to the termination of certain non statutory options, tax benefits recognized in prior periods from such stock compensation expense were reversed during the three and six months ended June 30, 2006. During the three and six months ended June 30, 2007, tax expense increased by approximately $5,000 and $210,000, respectively, as a result of a reversal of tax benefits recognized under SFAS 123(R).

The percentage tax rate reflected in the results of operations is based on the Company’s estimate of net income for the fiscal year 2007 at the end of each quarter. At June 30, 2007, without tax benefits realized through disqualifying dispositions and reversal of tax benefit recognized under SFAS 123(R), the full year estimate of the 2007 effective tax rate was approximately (29)%. However, with tax benefits realized through disqualifying dispositions and reversal of tax benefit recognized under SFAS 123(R), the effective tax rate was approximately (35)%.

10. LEGAL PROCEEDINGS

In May 2003, the Company received a letter from Linear Technology Corporation (“Linear Technology”) alleging that certain of its charge pump products infringed United States Patent No. 6,411,531 owned by Linear Technology. In August 2004, the Company received a letter from Linear Technology alleging that certain of its switching regulator products infringed United States Patent Nos. 5,481,178, 6,304,066 and 6,580,258. In response to these letters, the Company contacted Linear Technology to convey in good faith the belief that it does not infringe the patents in question. Subsequently, the Company became aware of a marketing campaign conducted by Linear Technology in which they sought to disrupt the Company’s business relationships and sales by suggesting to the Company’s customers that its products infringe the same U.S. patents mentioned in their two letters to the Company. As a result, in February 2006, the Company initiated a lawsuit against Linear Technology for unfair business practices, interference with existing and prospective customers and trade libel, as well as a declaration of patent invalidity and non-infringement. This case is currently stayed pending the outcome of the United States International Trade Commission (“USITC”) investigation described in the following paragraph.

In March 2006, the USITC responded to a petition filed by Linear Technology by initiating an examination to determine if certain of the Company’s products infringe certain patents owned by Linear Technology under Section 337 of the Tariff Act. The accused products include charge pumps and switching regulators and are similar to the products involved in the Company’s lawsuit with Linear Technology. The Company believes that none of its products infringe the Linear Technology patents in question. However, whether or not the Company prevails in this investigation, the Company has incurred and expects to incur significant legal expenses.

On May 22, 2007, Administrative Law Judge Sidney Harris of the USITC issued his Initial Determination, finding that all claims asserted by Linear Technology were either non-infringed or invalid. Based on this finding, Judge Harris ruled that none of the Company’s products should be subject to an exclusion order under Section

12

337 of the Tariff Act. Following normal procedure, the Initial Determination is now subject to possible review by the full ITC. Regardless of whether such review is undertaken, the Final Determination is expected to be issued by September 22, 2007.

Our net revenue in the second quarter of 2007 increased 18 percent compared to the second quarter of 2006 primarily as a result of continued increase in revenue from sale of our Display, Lighting Solutions, Voltage Regulation and DC/DC Conversion product families and increased sales in China. Gross profit in the second quarter of 2007 declined four percent compared to the second quarter of 2006 primarily due to unfavorable change in the product mix sold during the second quarter of 2007.

Cash, cash equivalents and short term investments as of June 30, 2007 increased $2 million to $110 million compared to December 31, 2006. We continue to be debt free as of June 30, 2007.

Critical Accounting Estimates

Our discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our financial statements requires us to make estimates and judgments that affect the reported amounts in our condensed consolidated financial statements. We evaluate our estimates on an on-going basis, including those related to our revenues, inventories, asset impairments, and income taxes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Although actual results have historically been reasonably consistent with management’s expectations, the actual results may differ from these estimates or our estimates may be affected by different assumptions or conditions.

Management believes that there have been no significant changes during the three and six months ended June 30, 2007 to the items that we disclosed as our critical accounting policies and estimates in the Management’s Discussion and Analysis of Financial Condition and Results of Operations section of our Annual Report on Form 10-K for the year ended December 31, 2006.

Comparison of Three and Six Months ended June 30, 2007 and June 30, 2006

Revenues

The following table illustrates our net revenue by principal product families:

	Three Months Ended June 30,								Six Months Ended June 30,
	2007				2006				2007				2006
	Amount		Percent of net revenue		Amount		Percent of net revenue		Amount		Percent of net revenue		Amount		Percent of net revenue
	(in thousands, except percentages)
Display and Lighting Solutions	$	15,277	59	%	$	12,230	56	%	$	27,178	58	%	$	22,696	57	%

Total	$	25,837	100	%	$	21,818	100	%	$	46,945	100	%	$	40,107	100	%

Our net revenue for the three months ended June 30, 2007 as compared to the three months ended June 30, 2006 increased $4 million, or 18 percent. This growth was primarily attributable to our Display, Lighting Solutions, Voltage Regulation and DC/DC Conversion product families, as a result of increased demand.

Geographically, sales to China increased due to higher demand from several of our distributors while sales to Taiwan and Europe decreased slightly.

Our net revenue for the six months ended June 30, 2007 as compared to the six months ended June 30, 2006 increased $7 million, or 17 percent. This growth was primarily attributable to our Display, Lighting Solutions, Voltage Regulation and DC/DC Conversion product families, as a result of increased demand.

Geographically, sales to China increased due to higher demand from several of our distributors while sales to Taiwan and Europe decreased slightly.

Gross Profit

	Three Months Ended June 30,											Six Months Ended June 30,
	2007			2006			Increase (Decrease)					2007			2006			Increase (Decrease)
	(in thousands, except percentages)
Net revenue	$	25,837		$	21,818		$	4,019		18.4	%	$	46,945		$	40,107		$	6,838		17.0	%
Cost of revenue		11,612			8,752			2,860		32.7	%		21,544			15,886			5,658		35.6	%
Gross profit	$	14,225		$	13,066							$	25,401		$	24,221
Gross profit margin percentage		55.1	%		59.9	%		(4.8	)%				54.1	%		60.4	%		(6.3	)%

Our gross margin was 55 percent for the three months ended June 30, 2007, compared to 60 percent for the three months ended June 30, 2006. This decrease was primarily due to an unfavorable change in product mix in the second quarter of 2007 as we sold more lower-margin products, partially offset by improved product yields in the second quarter of 2007.

During the second quarter of 2007, our gross inventory write-down was approximately $1.5 million, offset by the sale of $1.0 million of previously written down inventory. During the second quarter of 2006, our gross inventory write-down was approximately $0.6 million, offset by the sale of $0.6 million of previously written down inventory. The net effect of inventory write-down on our gross margin contributed to approximately 1.9% of decline in our gross margin during the second quarter of 2007. Previously, the net effect of inventory write-down on our gross margin has been flat.

17

Our gross margin was 54 percent for the six months ended June 30, 2007, compared to 60 percent for the six months ended June 30, 2006. This decrease was primarily due to an unfavorable change in product mix in the first six months of 2007 as we sold more lower-margin products and the amortization of acquired intangible assets during 2007, offset by improved product yields.

During the first six months of 2007, our gross inventory write-down was approximately $2.6 million, offset by the sale of $1.9 million of previously written down inventory. During the first six months of 2006, our gross inventory write-down was approximately $1.2 million, offset by the sale of $1.1 million of previously written down inventory. Historically, the net effect of inventory write-down on our gross margin has been flat.

Research and Development

	Three Months Ended June 30,											Six Months Ended June 30,
	2007			2006			Increase (Decrease)					2007			2006			Increase (Decrease)

Percentage of net revenue		29.3	%		26.5	%		2.8	%				31.3	%		29.5	%		1.8	%

Research and development expenses for the three months ended June 30, 2007 increased as compared to the three months ended June 30, 2006 primarily due to a $1.2 million increase in payroll and benefit related expenses as a result of higher headcount, a $0.4 million increase in information technology, occupancy and other research and development operation support expenses and $0.2 million increase in engineering expenses and outside services as we continued to develop new products. Research and development expense as a percentage of net revenue increased three percent.

Research and development expenses for the six months ended June 30, 2007 increased as compared to the six months ended June 30, 2006 primarily due to a $1.7 million increase in payroll and benefit related expenses as a result of higher headcount, a $0.5 million increase in information technology, occupancy and other research and development operation support expenses and a $0.4 million increase in engineering expenses and outside services as we continued to develop new products. Research and development expense as a percentage of net revenue increased two percent.

Sales, General and Administrative

	Three Months Ended June 30,											Six Months Ended June 30,
	2007			2006			Increase (Decrease)					2007			2006			Increase (Decrease)

Percentage of net revenue		25.5	%		26.8	%		(1.2	)%				27.3	%		27.5	%		(0.2	)%

Sales, general and administrative expenses for the three months ended June 30, 2007 increased as compared to the three months ended June 30, 2006 primarily due to a $1.1 million increase in payroll and benefit related expenses as a result of higher headcount offset by a $0.3 million decrease in professional services. Sales, general and administrative expense as a percentage of net revenue decreased one percent.

Sales, general and administrative expenses for the six months ended June 30, 2007 increased as compared to the six months ended June 30, 2006 primarily due to a $1.7 million increase in payroll, bonus and benefit related expenses as a result of higher headcount and a $0.5 million increase in stock compensation expenses offset by a $0.5 million decrease in professional services.

Patent Litigation

	Three Months Ended June 30,											Six Months Ended June 30,
	2007			2006			Increase (Decrease)					2007			2006			Increase (Decrease)
	(in thousands, except percentages)
Patent litigation	$	1,488		$	1,375		$	113		8.2	%	$	3,077		$	1,757		$	1,320		75.1	%
Percentage of net revenue		5.8	%		6.3	%		(0.5	)%				6.6	%		4.4	%		2.2	%

Patent litigation expenses for the three and six months ended June 30, 2007 increased as compared to the same periods in 2006 as we continue to defend our positions in litigation. We believe that we will incur additional litigation expenses in 2007 although at a lower rate than in the second half of 2006. For a description of our litigation please see Note 10, Legal Proceedings, to the Condensed Consolidated Financial Statements for further details.

Interest Income

Interest income from investments of approximately $1.4 million in the second quarter of 2007 was flat compared to interest and investment income in the second quarter of 2006.

Interest income from investments of approximately $2.7 million in the first six months of 2007 was flat compared to interest and investment income in the first six months of 2006.

Interest and Other Income (Expense), Net

Other expense in the first six months of 2007 was approximately $0.3 million, primarily consisting of a $0.3 million write-off of cumulative translation adjustment loss as a result of the liquidation of our Sweden branch office during the first quarter of 2007.

Provision for Income Taxes

We recorded a tax provision of approximately $813,000 and $266,000 for the three months ended June 30, 2007 and 2006, respectively. Although we incurred a loss before income tax on a worldwide consolidated basis for the three and six months ended June 30, 2007, we remained taxable in certain jurisdictions where there were taxable profits. As a result, we recorded a tax provision for the three and six months ended June 30, 2007. For the six months ended June 30, 2007 and 2006, we recorded a tax provision of approximately $944,000 and $312,000, respectively. We account for income taxes under the provisions of SFAS No. 109, “Accounting for Income Taxes.” Under this method, we determine deferred tax assets and liabilities based upon the differences between the financial statement and tax bases of our assets and liabilities using tax rates in effect for the year in which we expect the differences to affect taxable income. We adopted SFAS 123(R) as of January 1, 2006, and, as a result, incurred significant stock-based compensation expense, including amounts related to incentive stock options for which no corresponding tax benefit is recognized unless a disqualifying disposition occurs. Disqualifying dispositions result in a reduction of income tax expense in the quarter when the disqualifying disposition occurs in an amount equal to the tax benefit relating to previously expensed stock compensation. During the three months ended June 30, 2007 and 2006, tax expense was reduced by approximately $16,000 and $10,000, respectively, as a result of disqualifying dispositions. During the six months ended June 30, 2007 and 2006, tax expense was reduced by approximately $37,000 and $101,000, respectively, as a result of disqualifying dispositions. As of June 30, 2007, we had not recorded tax benefits related to tax deductions in excess of previously expensed stock compensation because of our net operating loss carry forward. Due to the termination of certain non statutory options, tax benefits recognized in prior periods from such stock compensation expense were reversed during the three and six months ended June 30, 2006. During the three and six months ended June 30, 2007, tax expense increased by approximately $5,000 and $210,000, respectively, as a result of a reversal of tax benefits recognized under SFAS 123(R).

The percentage tax rate reflected in the results of operations is based on our estimate of net income for the fiscal year 2007 at the end of each quarter. At June 30, 2007, without tax benefits realized through disqualifying dispositions and reversal of tax benefit recognized under SFAS 123(R), the full year estimate of the 2007 effective tax rate was approximately (29)%. However, with tax benefits realized through disqualifying dispositions and reversal of tax benefit recognized under SFAS 123(R), the effective tax rate was approximately (35)%.

Recently Issued Accounting Pronouncements

FIN 48

On July 13, 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — An Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in an entity’s financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes” and prescribes a recognition threshold and measurement attributes for financial statement disclosure of tax positions taken or expected to be taken on a tax return. Under FIN 48, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more likely than not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, FIN 48 provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. FIN 48 is effective for fiscal years beginning after December 15, 2006.

We adopted the provisions of FIN 48 on January 1, 2007. The total amount of unrecognized tax benefits as of the date of adoption was approximately $2,417,000. If such unrecognized tax benefits are recognized, the effective tax rate would be affected. As a result of the implementation of FIN 48, we recognized approximately $550,000 of a net decrease in the liability for unrecognized tax benefits which was accounted for as follows:

Increase in Retained Earnings (cumulative effect)	$	848,000
Decrease in Retained Earnings (cumulative effect)	$	(305,000	)
Reduction in Deferred Tax Assets	$	7,000
Decrease in Liability	$	550,000

During the three and six months ended June 30, 2007, we increased our total amount of unrecognized tax benefits to approximately $2,579,000, including an accrual of interest and penalties of approximately $22,000. We recognize interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the year ended December 31, 2006, we recognized approximately $16,000 in penalties and interest. During the years ended December 31, 2005 and 2004, no penalties and interest were recognized. There had been no payment of interest and penalties accrued at December 31, 2006. Upon adoption of FIN 48 on January 1, 2007, we increased our accrual for interest and penalties to approximately $95,000. During the three and six months ended June 30, 2007, we increased our accrual for interest and penalties to approximately $117,000.

We are subject to taxation in the United States and various states and foreign jurisdictions. Our tax years for 1997 through 2006 are subject to examination by the tax authorities. Currently, an estimate of the range of the reasonably possible change in unrecognized tax benefits in the next 12 months cannot be made. We are no longer subject to foreign examinations by tax authorities for years before 2001.

SFAS 159

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”), which permits entities to choose to measure many financial instruments and certain other items at fair value. The objective is to improve financial reporting by providing entities with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently without having to apply complex hedge accounting provisions. SFAS 159 applies to all entities and is effective for fiscal years beginning after November 15, 2007. We do not believe SFAS 159 will have a material impact on our financial statements.

Net increase (decrease) on cash and cash equivalents	$	(6,697	)	$	(21,565	)	$	14,868		-69	%

Our cash, cash equivalents and short term investments were $109.9 million as of June 30, 2007 and $107.7 million as of December 31, 2006.

Net Cash Provided by Operating Activities

Net cash provided by operating activities was $3.3 million for the six months ended June 30, 2007. Net loss of $3.6 million was adjusted for non-cash charges consisting primarily of $1.4 million of depreciation and amortization expense and $3.5 million of stock-based compensation expense. Accounts payable and accrued liabilities balance increased $4.6 million due to increased purchases of materials and services to meet expected demand. Inventory increased $3 million as a result of anticipated sale during the second half of 2007. Accounts receivable balance increased $0.8 million due to higher revenue during the period.

Net cash provided by operating activities was $3.6 million for the six months ended June 30, 2006, which primarily consisted of net income of $2.0 million, $3.1 million from increases in accounts payable and $0.5 million from reductions in prepaid and other assets, which were offset by $2.4 million of increases in inventories, $2.1 million of increase in accounts receivable, $1.2 million of increase in deferred tax assets and $0.4 million from decreases of accrued liabilities. In addition, we had an aggregate of $2.9 million of stock-based compensation expense and $0.8 million of depreciation and amortization expense. Our accounts payable and inventories have increased primarily as a result of increased purchases of materials and production to meet expected demand. Our prepaid and other assets have decreased primarily due to continued amortization of insurance premiums over the term of our insurance policies. Our accounts receivable balance increased due to increased sales during the quarter. Our stock-based compensation expenses have risen as a result of our adoption of SFAS 123(R) and the increased number of options granted to employees and consultants. Depreciation and amortization expenses have also risen and we expect that this will continue to rise as we invest in research and development and infrastructure.

Net Cash Used in Investing Activities

Net cash used in investing activities was $10.3 million in the six months ended June 30, 2007, primarily as a result of a net cash outflow of $8.9 million from purchases and maturities of our short-term investment and $1.4 million used to purchase testing and other equipment and to support our internal infrastructure growth.

Net cash used in our investing activities was $26.6 million in the six months ended June 30, 2006. The increase in cash usage from investing activities was primarily due to $25.3 million for purchases of short term investments, $0.9 million for purchases of long-term private equity investments and $0.9 million for purchases of various engineering software and to support our internal infrastructure growth.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $0.4 million in the six months ended June 30, 2007, primarily as a result of $0.5 million net proceeds from exercises of common stock options.

21

Net cash provided by our financing activities was $1.4 million in the six months ended June 30, 2006, which primarily consisted of $0.9 million of net proceeds from exercises of common stock options and their related tax benefit of $0.5 million.

Liquidity

We believe our existing cash, cash equivalents and short-term investment balances, as well as cash expected to be generated from operating activities, will be sufficient to meet our anticipated cash needs for at least the next 12 months.

Our long-term future capital requirements will depend on many factors, including our level of revenue, the timing and extent of spending to support our product development efforts, the expansion of sales and marketing activities, the timing of our introductions of new products, the costs to ensure access to adequate manufacturing capacity, our level of acquisition activity or other strategic transactions, the continuing market acceptance of our products and the amount and intensity of our litigation activity. We could be required, or could elect, to seek additional funding through public or private equity or debt financing and additional funds may not be available on terms acceptable to us or at all.

Off Balance Sheet Arrangements

We have not entered into any transactions with unconsolidated entities whereby we have financial guarantees, subordinated retained interests, derivative instruments or other contingent arrangements that expose us to material continuing risks, contingent liabilities, or any other obligation under a variable interest in an unconsolidated entity that provides financing, liquidity, market risk or credit risk support to us.

Contractual Obligations

The following table describes our principal contractual cash obligations as of June 30, 2007:

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

At June 30, 2007, we had cash and cash equivalents totaling $51.4 million, compared to $58.1 million at December 31, 2006. At June 30, 2007, we had $58.5 million in short-term investments as compared to $49.6 million at December 31, 2006. Cash equivalents have an original or remaining maturity when purchased of 90 days or less; short-term investments generally have an original or remaining maturity when purchased of greater than 90 days. The taxable equivalent interest rates for the three and six months ended June 30, 2007, on those cash equivalents and short-term investments average approximately 5.30% and 5.33%, respectively. The primary objective of our investment activities is to preserve principal while maximizing income without significantly increasing risk. Some of the securities in which we invest may be subject to market risk. This means that a change in prevailing interest rates may cause the principal amount of the investment to fluctuate. To minimize this risk, we may maintain our portfolio of cash equivalents and short-term investments in a variety of securities, including commercial paper, money market funds, debt securities and certificates of deposit.

A hypothetical increase in market interest rates of 100 basis points from the market rates in effect at June 30, 2007 would cause the fair value of these investments to decrease by an immaterial amount, which would not have significantly impacted our financial position or results of operations. Declines in interest rates over time will result in lower interest income. Based upon our analysis the fair values did not change materially as our investments are of short duration.

ITEM 4. CONTROLS AND PROCEDURES

(a) Evaluation of Disclosure Controls and Procedures

Our management evaluated, with the participation of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. As of June 30, 2007 our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, concluded that our disclosure controls and procedures were effective to ensure that information that we are required to disclose in reports that we file or submit under the Securities Exchange Act of 1934 were recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms.

(b) Changes in Internal Controls Over Financial Reporting

There was no change in our internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the second quarter of 2007 covered by this Quarterly Report of Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In May 2003, we received a letter from Linear Technology Corporation alleging that certain of our charge pump products infringed United States Patent No. 6,411,531 owned by Linear Technology. In August 2004, we received a letter from Linear Technology alleging that certain of our switching regulator products infringed United States Patent Nos. 5,481,178, 6,304,066 and 6,580,258. In response to these letters, we contacted Linear Technology to convey our good faith belief that we do not infringe the patents in question. Subsequently, we became aware of a marketing campaign conducted by Linear Technology in which they sought to disrupt our business relationships and sales by suggesting to our customers that our products infringe the same U.S. patents mentioned in their two letters to us. As a result, in February 2006, we initiated a lawsuit against Linear Technology for unfair business practices, interference with existing and prospective customers and trade libel, as well as a declaration of patent invalidity and non-infringement. This case is currently stayed pending the outcome of the United States International Trade Commission (“USITC”) investigation described in the following paragraph.

In March 2006, the USITC responded to a petition filed by Linear Technology by initiating an examination to determine if certain of our products infringe certain patents owned by Linear Technology under Section 337 of the Tariff Act. The accused products include charge pumps and switching regulators and are similar to the products involved in our lawsuit with Linear Technology. We believe that none of our products infringe the Linear Technology patents in question. However, whether or not we prevail in this investigation, we have incurred and expect to incur significant legal expenses.

On May 22, 2007, Administrative Law Judge Sidney Harris of the USITC issued his Initial Determination, finding that all claims asserted by Linear were either non-infringed or invalid. Based on this finding, Judge Harris ruled that none of AnalogicTech’s products should be subject to an exclusion order under Section 337 of the Tariff Act. Following normal procedure, the Initial Determination is now subject to possible review by the full ITC. Regardless of whether such review is undertaken, the Final Determination is expected to be issued by September 22, 2007.

ITEM 1A. RISK FACTORS

Risks Related To Our Business

Our customers may cancel their orders, change production quantities or delay production, and if we fail to forecast demand for our products accurately, we may incur product shortages, delays in product shipments or excess or insufficient product inventory.

We generally do not obtain firm, long-term purchase commitments from our customers. Because production lead times often exceed the amount of time required to fulfill orders, we often must build in advance of orders, relying on an imperfect demand forecast to project volumes and product mix. Our demand forecast accuracy can be adversely affected by a number of factors, including inaccurate forecasting by our customers, changes in market conditions, new part introductions by our competitors that lead to our loss of previous design wins, adverse changes in our product order mix and demand for our customers’ products or models. China, in particular, is an emerging market where forecasting by our distributors is not accurate, and there can be rapid changes in the distribution system and market conditions. Even after an order is received, our customers may cancel these orders or request a decrease in production quantities. Any such cancellation or decrease subjects us to a number of risks, most notably that our projected sales will not materialize on schedule or at all, leading to unanticipated revenue shortfalls and excess or obsolete inventory which we may be unable to sell to other customers. Alternatively, if we are unable to project customer requirements accurately, we may not build enough products, which could lead to delays in product shipments and lost sales opportunities in the near term, as well as force our customers to identify alternative sources, which could affect our ongoing relationships with these customers. We have in the past had customers dramatically increase their requested production quantities with little or no advance notice and after they had submitted their original order. We have on occasion been unable to fulfill these revised orders within the time period requested. Either underestimating or overestimating demand would lead to excess, obsolete or insufficient inventory, which could harm our operating results, cash flow and financial condition, as well as our relationships with our customers.

24

We receive a substantial portion of our revenues from a small number of customers, and the loss of, or a significant reduction in, orders from those customers or our other largest customers would adversely affect our operations and financial condition.

We receive a substantial portion of our revenues from two of our customers, LG Electronics Inc. of South Korea and Samsung of South Korea. We received an aggregate of approximately 21% and 11% of our revenue from LG and Samsung for the second quarter of 2007 and 27% and 14% in the second quarter of 2006, respectively. We anticipate that we will continue to be dependent on LG and Samsung for a significant portion of our revenue in the immediate future; however, we do not have long-term contractual purchase commitments from LG and Samsung, and we cannot assure you that LG and Samsung will continue to be our customers.

We received an aggregate of approximately 80% of our revenues from our ten largest customers for the second quarter of 2007. Any action by LG and Samsung or any of our other largest customers that affects our orders, product pricing or vendor status could significantly reduce our revenues and harm our financial results. In the future, our sales to LG and Samsung or our other large customers will continue to be susceptible to this type of quarterly fluctuation as our customers manage their inventories, principally for seasonal variations. In particular, our customers’ increase in inventory of our products in advance of this peak buying season for wireless handsets often leads to sequentially lower sales of our products in the first calendar quarter and, potentially, late in the fourth calendar quarter. Because our largest customers account for such a significant part of our business, the loss of, or a decline in sales to, any of our major customers would negatively impact our business.

Our operating results have fluctuated in the past and we expect our operating results to continue to fluctuate.

Our revenues are difficult to predict and have varied significantly in the past from period to period. We expect our revenues and expense levels to continue to vary in the future, making it difficult to predict our future operating results. In particular, we experience seasonality and variability in demand for our products as our customers manage their inventories. Our customers tend to increase inventory of our products in anticipation of the peak fourth quarter buying season for the mobile consumer electronic devices in which our products are used, which often leads to sequentially lower sales of our products in the first calendar quarter and, potentially, late in the fourth calendar quarter.

Additional factors that could cause our results to fluctuate include:

• the forecasting, scheduling, rescheduling or cancellation of orders by our customers, particularly in China and other emerging markets;

• costs associated with litigation, especially related to intellectual property;

• liquidity and cash flow of our distributors and end-market customers;

• changes in manufacturing costs, including wafer, test and assembly costs, and manufacturing yields, product quality and reliability;

• the timing and availability of adequate manufacturing capacity from our manufacturing suppliers;

• our ability to successfully define, design and release new products in a timely manner that meet our customers’ needs;

• the timing, performance and pricing of new product introductions by us and by our competitors;

• general economic conditions in the countries where we operate or our products are used;

• changes in exchange rates, interest rates, tax rates and tax withholding;

• geopolitical stability, especially affecting China, Taiwan and Asia in general; and

• changes in domestic and international tax laws.

Unfavorable changes in any of the above factors, most of which are beyond our control, could significantly harm our business and results of operations.

25

We may be unsuccessful in developing and selling new products or in penetrating new markets.

We operate in a dynamic environment characterized by rapidly changing technologies and industry standards and technological obsolescence. Our competitiveness and future success depends on our ability to design, develop, manufacture, assemble, test, market and support new products and enhancements on a timely and cost-effective basis. A fundamental shift in technologies in any of our product markets could harm our competitive position within these markets. Our failure to anticipate these shifts, to develop new technologies or to react to changes in existing technologies could materially delay our development of new products, which could result in product obsolescence, decreased revenues and a loss of design wins to our competitors. The success of a new product depends on accurate forecasts of long-term market demand and future technological developments, as well as on a variety of specific implementation factors, including:

• effective marketing, sales and service;

• timely and efficient completion of process design and device structure improvements and implementation of manufacturing, assembly and test processes; and

• the quality, performance and reliability of the product.

If we fail to introduce new products or penetrate new markets, our revenues will likely decrease over time and our financial condition could suffer.

Due to defects and failures that may occur, our products may not meet specifications, which may cause customers to return or stop buying our products and may expose us to product liability claims.

Our customers generally establish demanding specifications for quality, performance and reliability that our products must meet. Integrated circuits, or ICs, as complex as ours often encounter development delays and may contain undetected defects or failures when first introduced or after commencement of commercial shipments, which might require product replacement or recall. For example, in 2003 one of our low-dropout linear regulator products that we had been shipping for two years developed unacceptably high failure rates, which caused us to direct our engineering personnel from other priorities to redesign the product. If defects and failures occur in our products during the design phase or after, we could experience lost revenues, increased costs, including warranty expense and costs associated with customer support, delays in or cancellations or rescheduling of orders or shipments, or product returns or discounts, any of which would harm our operating results. We cannot assure you that we will have sufficient resources, including any available insurance, to satisfy any asserted claims.

The nature of the design process requires us to incur expenses prior to earning revenues associated with those expenses, and we will have difficulty selling our products if system designers do not design our products into their electronic systems.

We devote significant time and resources in working with our customers’ system designers to understand their future needs and to provide products that we believe will meet those needs. If a customer’s system designer initially chooses a competitor’s product for a particular electronic system, it becomes significantly more difficult for us to sell our products for use in that electronic system because changing suppliers can involve significant cost, time, effort and risk for our customers.

We often incur significant expenditures in the development of a new product without any assurance that our customers’ system designers will select our product for use in their electronic systems. We often are required to anticipate which product designs will generate demand in advance of our customers expressly indicating a need for that particular design. In some cases, there is minimal or no demand for our products in our anticipated target applications. Even if our products are selected by our customers’ system designers, a substantial period of time will elapse before we generate revenues related to the significant expenses we have incurred. The reasons for this delay generally include the following elements of our product sales and development cycle timeline and related influences:

• our customers usually require a comprehensive technical evaluation of our products before they incorporate them into their electronic systems;

• it can take up to 12 months from the time our products are selected to complete the design process;

• it can take an additional nine to 12 months or longer to complete commercial introduction of the electronic systems that use our products, if they are introduced at all;

• original equipment manufacturers typically limit the initial release of their electronic systems to evaluate performance and consumer demand; and

26

• The development and commercial introduction of products incorporating new technology are frequently delayed.

We estimate that the overall sales and development cycle timeline of an average product is approximately 16 months.

Additionally, even if system designers use our products in their electronic systems, we cannot assure you that these systems will be commercially successful. As a result, we are unable to accurately forecast the volume and timing of our orders and revenues associated with any new product introductions.

Any increase in the manufacturing cost of our products could reduce our gross margins and operating profit.

The semiconductor business exhibits ongoing competitive pricing pressure from customers and competitors. Accordingly, any increase in the cost of our products, whether by adverse purchase price variances or adverse manufacturing cost variances, will reduce our gross margins and operating profit. For example, if we do not incorporate the partially fabricated wafers held for us by our suppliers into our products in a timely fashion, we may still become obligated to purchase these materials, which may reduce our gross margins. We do not have many long-term supply agreements with our manufacturing suppliers and, consequently, we may not be able to obtain price reductions or anticipate or prevent future price increases from our suppliers.

The average selling price of our products may decline, or a change in the mix of product orders may occur, either of which could reduce our gross margins.

During a power management product’s life, its selling price tends to decrease for a particular application. As a result, to maintain gross margins on our products, we must continue to identify new applications for our products, reduce manufacturing costs for our existing products and introduce new products. If we are unable to identify new, high gross margin applications for our existing products, reduce our production costs or sell new, high gross margin products, our gross margins will suffer. A sustained reduction in our gross margins could harm our future operating results, cash flow and financial condition, which could lead to a significant drop in the price of our common stock.

Because we receive a substantial portion of our revenues through distributors, their financial viability and ability to access the capital markets could impact our ability to continue to do business with them and could result in lower revenues, which could adversely affect our operating results and our customer relationships.

We obtain a portion of our revenues through sales to distributors located in Asia who act as our fulfillment representatives. Sales to distributors accounted for 43% and 37% of our revenues for the second quarters of 2007 and 2006, respectively. In the normal course of their operation as fulfillment representatives, these distributors typically perform functions such as order scheduling, shipment coordination, inventory stocking, payment and collections and, when applicable, currency exchange between purchasers of our products and these distributors. Our distributors’ compensation for these functions is reflected in the price of the products we sell to these distributors. Many of our current distributors also serve as our sales representatives procuring orders for us to fill directly. If these distributors are unable to pay us in a timely manner or if we anticipate that they will not pay us, we may elect to withhold future shipments, which could adversely affect our operating results. If one of our distributors experiences severe financial difficulties, becomes insolvent or declares bankruptcy, we could lose product inventory held by that distributor and we could be required to write off the value of any receivables owed to us by that distributor. We could also be required to record bad debt expense in excess of our reserves. In the future, we may not be successful in recognizing these indications or in finding replacement distributors in a timely manner, or at all, which could harm our operating results, cash flow and financial condition.

Our distributor arrangements often require us to accept product returns and to provide price protection and if we fail to properly estimate our product returns and price protection reserves, this may adversely impact our reported financial information.

A substantial portion of our sales are made through third-party distribution arrangements, which include stock rotation rights that generally permit the return of up to 5% of the previous six months’ purchases. We generally accept these returns in the second and fourth quarter of each annual period. Our arrangements with our

27

distributors typically also include price protection provisions if we reduce our list prices. We record estimated returns at the time of shipment, and we record reserves for price protection at the time we decide to reduce our list prices. In the future, we could receive returns or claims that are in excess of our estimates and reserves, which could harm our operating results.

Our distributor arrangements often require us to accept returns of unsold products if contractual arrangements with a distributor are terminated, which could harm our operating results or, if we fail to take steps, could harm our relationship with these distributors and lead to a loss of revenues.

If our relationship with any of our distributors deteriorates or terminates, it could lead to a temporary or permanent loss of revenues until a replacement sales channel can be established to service the affected end-user customers, as well as inventory write-offs or accounts receivable write-offs. We may not be successful in finding suitable alternative distributors and this could adversely affect our ability to sell in certain locations or to certain end-user customers. We also may be obligated to repurchase unsold products from a distributor if we decide to terminate our relationship with that distributor.

Our current backlog may not be indicative of future sales.

Due to the nature of our business, in which order lead times may vary, and the fact that customers are generally allowed to reschedule or cancel orders on short notice, we believe that our backlog is not necessarily a good indicator of our future sales. Our quarterly revenues also depend on orders booked and shipped in that quarter. Because our lead times for the manufacturing of our products generally take six to ten weeks, we often must build in advance of orders. This exposes us to certain risks, most notably the possibility that expected sales will not occur, which may lead to excess inventory, and we may not be able to sell this inventory to other customers. In addition, we supply LG, one of our largest customers, through its central hub and we do not record backlog with respect to the products we ship to the hub. Therefore, our backlog may not be a reliable indicator of future sales.

If consumer demand for mobile consumer electronic devices declines, our revenues will decrease.

Our products are used primarily in the mobile consumer electronic devices market. For the foreseeable future, we expect to see the significant majority of our revenues continue to come from this market, especially in wireless handsets. If consumer demand for these products declines, our revenues will decrease. If we are unsuccessful in identifying alternative markets for our products in a timely manner, our operating results will suffer dramatically.

Substantially all of our manufacturing suppliers, customers and operations are located in Asia, which subjects us to additional risks, including regional economic influences, logistical complexity, political instability, natural disasters including earthquakes and currency fluctuations.

We conduct, and expect to continue to conduct, almost all of our business with companies that are located outside the United States. Based on ship-to locations, we derived approximately 98% of our revenues from customers outside of the United States in the second quarters of 2007 and 2006. Approximately 96% and 94% of our revenues came from customers in Asia, particularly South Korea, Taiwan, China and Japan, in the second quarters of 2007 and 2006, respectively. A vast majority of our contract manufacturing operations are located in South Korea, Taiwan, Malaysia and China. In addition, we have a design center in Shanghai. As a result of our international focus, we face several challenges, including:

• increased complexity and costs of managing international operations;

• longer and more difficult collection of receivables;

• political and economic instability;

• limited protection of our intellectual property;

• unanticipated changes in local regulations, including tax regulations;

• timing and availability of import and export licenses; and

• foreign currency exchange fluctuations relating to our international operating activities.

Our corporate headquarters in Sunnyvale, California, our operations office in Chupei, Taiwan, and the production facilities of one of our wafer fabrication suppliers and several of our assembly and test suppliers in

28

Hsinchu and across Taiwan are located near seismically active regions and are subject to periodic earthquakes. We do not maintain earthquake insurance and our business could be damaged in the event of a major earthquake or other natural disaster.

In addition to risks in our operations from natural disasters, our customers are also subject to these risks. Any disaster impacting our customers could result in loss of orders, delay of business and temporary regional economic recessions.

We are also more susceptible to the regional economic impact of health crises. Because we anticipate that we will continue to rely heavily on foreign companies or U.S. companies operating in Asia for our future growth, the above risks and issues that we do not currently anticipate could adversely affect our ability to conduct business and our results of operations.

We outsource our wafer fabrication, testing, packaging, warehousing and shipping operations to third parties, and rely on these parties to produce and deliver our products according to requested demands in specification, quantity, cost and time.

We rely on third parties for substantially all of our manufacturing operations, including wafer fabrication, wafer probe, wafer thinning, assembly, final test, warehousing and shipping. We depend on these parties to supply us with material of a requested quantity in a timely manner that meets our standards for yield, cost and manufacturing quality. Any problems with our manufacturing supply chain could adversely impact our ability to ship our products to our customers on time and in the quantity required, which in turn could cause an unanticipated decline in our sales and possibly damage our customer relationships.

Our products are manufactured at a limited number of locations. If we experience manufacturing problems at a particular location, we would be required to transfer manufacturing to a backup supplier. Converting or transferring manufacturing from a primary supplier to a backup fabrication facility could be expensive and could take as long as six to 12 months. During such a transition, we would be required to meet customer demand from our then-existing inventory, as well as any partially finished goods that can be modified to the required product specifications. We do not seek to maintain sufficient inventory to address a lengthy transition period because we believe it is uneconomical to keep more than minimal inventory on hand. As a result, we may not be able to meet customer needs during such a transition, which could delay shipments, cause a production delay or stoppage for our customers, result in a decline in our sales and damage our customer relationships.

In addition, a significant portion of our sales is to customers that practice just-in-time order management from their suppliers, which gives us a very limited amount of time in which to process and complete these orders. As a result, delays in our production or shipping by the parties to whom we outsource these functions could reduce our sales, damage our customer relationships and damage our reputation in the marketplace, any of which could harm our business, results of operations and financial condition.

The loss of any of our key personnel could seriously harm our business, and our failure to attract or retain specialized technical and management talent could impair our ability to grow our business.

The loss of services of one or more of our key personnel could seriously harm our business. In particular, our ability to define and design new products, gain new customers and grow our business depends on the continued contributions of Richard K. Williams, our President, Chief Executive Officer and Chief Technical Officer, as well as our senior level sales, operations, technology and engineering personnel. Our future growth will also depend significantly on our ability to recruit and retain qualified and talented managers and engineers, along with key manufacturing, quality, sales and marketing staff members. There remains intense competition for these individuals in our industry, especially those with power and analog semiconductor design and applications expertise. We cannot assure you we will be successful in finding, hiring and retaining these individuals. If we are unable to recruit and retain such talent, our product and technology development, manufacturing, marketing and sales efforts could be impaired.

We compete against companies with substantially greater financial and other resources, and our market share or gross margins may be reduced if we are unable to respond to competitive challenges effectively.

The analog, mixed-signal, or analog with digital, and power management semiconductor industry in which we operate is highly competitive and dynamic, and we expect it to remain so. Our ability to compete effectively depends on defining, designing and regularly introducing new products that meet or anticipate the power

29

management needs of our customers’ next-generation products and applications. We compete with numerous domestic and international semiconductor companies, many of which have greater financial and other resources with which to pursue marketing, technology development, product design, manufacturing, quality, sales and distribution of their products.

We consider our primary competitors to be Maxim Integrated Products, Inc., Linear Technology Corporation, Texas Instruments Incorporated, Semtech Corporation and National Semiconductor Corporation. We expect continued competition from existing suppliers as well as from new entrants into the power management semiconductor market. Our ability to compete depends on a number of factors, including:

• our success in identifying new and emerging markets, applications and technologies, and developing power management solutions for these markets;

• our products’ performance and cost effectiveness relative to that of our competitors’ products;

• our ability to deliver products in large volume on a timely basis at a competitive price;

• our success in utilizing new and proprietary technologies to offer products and features previously not available in the marketplace;

• our ability to recruit application engineers and designers; and

• our ability to protect our intellectual property.

We cannot assure you that our products will compete favorably or that we will be successful in the face of increasing competition from new products and enhancements introduced by our existing competitors or new companies entering this market.

Assertions by third parties of infringement by us of their intellectual property rights could result in significant costs, reduce sales of our products and cause our operating results to suffer.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights and positions, which has resulted in protracted and expensive litigation for many companies. We have in the past received, and expect that in the future we may receive, communications from various industry participants alleging our infringement of their patents, trade secrets or other intellectual property rights. Any lawsuits resulting from such allegations could subject us to significant liability for damages and invalidate our proprietary rights. Any potential intellectual property litigation also could force us to do one or more of the following:

• stop selling products or using technology that contain the allegedly infringing intellectual property;

• incur significant legal expenses;

• pay damages to the party claiming infringement;

• redesign those products that contain the allegedly infringing intellectual property; and

• attempt to obtain a license to the relevant intellectual property from third parties, which may not be available on reasonable terms or at all.

We initiated a lawsuit against Linear Technology Corporation in February 2006 for unfair business practices, interference with existing and prospective customers and trade libel, as well as a declaration of patent invalidity and non-infringement. In this case, we are seeking to prevent Linear Technology from continuing a marketing campaign designed to disrupt our business relationships and sales by suggesting to our customers that our products infringe several U.S. patents owned by Linear Technology. As we informed Linear Technology in 2003 and 2004, and as discussed in our prior public filings, we believe that none of our products infringe the patents in question. However, whether or not we prevail in this lawsuit, we expect to incur significant legal expenses related to this case. If we are unsuccessful in this case, our business and our ability to compete in foreign markets could be harmed, and we could be enjoined from selling the accused products in the United States, either directly or indirectly, which could have a material adverse impact on our revenues, financial condition, results of operations and cash flows.

In February 2006, in a related action, Linear Technology petitioned the United States International Trade Commission (“USITC”) requesting that the USITC initiate an investigation to determine if certain of our products infringe certain patents owned by Linear Technology under Section 337 of the Tariff Act. The patents

30

involved in this action are a subset of the patents involved in the lawsuit that we filed against Linear Technology. The accused products include charge pumps and switching regulators and are similar to the products involved in our lawsuit with Linear Technology. As with any litigated matter, we expect to incur expenses defending this action. If we are unsuccessful in this case, our business and our ability to compete in foreign markets could be harmed, and we could be enjoined from selling the accused products in the United States, either directly or indirectly, which could have a material adverse impact on our revenues, financial condition, results of operations and cash flows.

On May 22, 2007, Administrative Law Judge Sidney Harris of the USITC issued his Initial Determination, finding that all claims asserted by Linear Technology were either non-infringed or invalid. Based on this finding, Judge Harris ruled that none of our products should be subject to an exclusion order under Section 337 of the Tariff Act. Following normal procedure, the Initial Determination is now subject to possible review by the full ITC. Regardless of whether such review is undertaken, the Final Determination is expected to be issued by September 22, 2007.

Uncertainty over the outcome of our litigation with Linear Technology may cause our customers or potential customers to elect not to include our products that are the subject of this litigation into the design of their systems. Once a customer’s system designer initially chooses a competitor’s product for a particular electronic system, it becomes significantly more difficult for us to sell our products for use in that electronic system, because changing suppliers can involve significant cost, time, effort and risk for our customers. As a result, our litigation with Linear Technology or any similar future litigation may reduce both our current and future revenues.

Our failure to protect our intellectual property rights adequately could impair our ability to compete effectively or to defend ourselves from litigation, which could harm our business, financial condition and results of operations.

We rely primarily on patent, copyright, trademark and trade secret laws, as well as confidentiality and non-disclosure agreements to protect our proprietary technologies and know-how. While we have approximately 50 patents issued or allowed in the United States or foreign countries and a larger number of pending applications, the rights granted to us may not be meaningful or provide us with any commercial advantage. For example, these patents could be challenged or circumvented by our competitors or be declared invalid or unenforceable in judicial or administrative proceedings. The failure of our patents to adequately protect our technology might make it easier for our competitors to offer similar products or technologies. Our foreign patent protection is generally not as comprehensive as our U.S. patent protection and may not protect our intellectual property in some countries where our products are sold or may be sold in the future. Even if foreign patents are granted, effective enforcement in foreign countries may not be available. Many U.S.-based companies have encountered substantial intellectual property infringement in foreign countries, including countries where we sell products.

Monitoring unauthorized use of our intellectual property is difficult and costly. It is possible that unauthorized use of our intellectual property may occur without our knowledge. We cannot assure you that the steps we have taken will prevent unauthorized use of our intellectual property. Our failure to effectively protect our intellectual property could reduce the value of our technology in licensing arrangements or in cross-licensing negotiations, and could harm our business, results of operations and financial condition. We may in the future need to initiate infringement claims or litigation. Litigation, whether we are a plaintiff or a defendant, can be expensive, time-consuming and may divert the efforts of our technical staff and managerial personnel, which could harm our business, whether or not such litigation results in a determination favorable to us.

We do not expect to sustain our recent growth rate, and we may not be able to manage any future growth effectively.

We have experienced significant growth in a short period of time. Our revenues have increased from approximately $1.0 million in 2001 to $81.2 million in 2006. We do not expect to achieve similar growth rates in future periods. You should not rely on our operating results for any prior quarterly or annual periods as an indication of our future operating performance. If we are unable to maintain adequate revenue growth, our financial results could suffer and our stock price could decline.

We have also grown from 110 employees on January 1, 2004 to 284 employees on June 30, 2007, with many located in regional and international offices. Our international growth may subject us to income and transaction taxes in the United States and in multiple foreign locations. Our future effective tax rates could be

31

affected by changes in our U.S. and foreign tax estimates and liabilities, or changes in tax laws or the interpretation of such tax laws. If additional taxes are assessed against us, our operating results or financial condition could be materially affected.

Our expansion has placed a significant strain on our management, personnel, systems and resources. Any future expansion is likely to result in additional strain on our managerial infrastructure. To manage our growth successfully and handle the responsibilities of being a public company, we believe we must effectively:

• recruit, hire, train and manage additional qualified engineers for our research and development activities, especially in the positions of design engineering, product and test engineering, and applications engineering;

• continue to implement and improve adequate administrative, financial and operational systems, procedures and controls; and

• enhance our information technology support for enterprise resource planning and design engineering by adapting and expanding our systems and tool capabilities, and properly training new hires as to their use.

If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new products, our introduction of derivative products may be delayed and we may fail to satisfy customer requirements, maintain product quality, execute our business plan or respond to competitive pressures.

Any acquisitions we make could disrupt our business, result in integration difficulties or fail to realize anticipated benefits, which could adversely affect our financial condition and operating results.

We may choose to acquire companies, technologies, assets and personnel that are complementary to our business, including for the purpose of expanding our new product design capacity, introducing new design, market or application skills or enhancing and expanding our existing product lines. In October 2006, we acquired Analog Power Semiconductor Corporation and related assets and personnel, primarily located in Shanghai, China. Acquisitions involve numerous risks, including the following:

• difficulties in integrating the operations, systems, technologies, products and personnel of the acquired companies;

• diversion of management’s attention from normal daily operations of the business and the challenges of managing larger and more widespread operations resulting from acquisitions;

• difficulties in entering markets in which we may have no or limited direct prior experience and where competitors may have stronger market positions;

• the potential loss of key employees, customers, distributors, suppliers and other business partners of the companies we acquire following and continuing after announcement of acquisition plans;

• improving and expanding our management information systems to accommodate expanded operations;

• insufficient revenue to offset increased expenses associated with acquisitions; and

• addressing unforeseen liabilities of acquired businesses.

Acquisitions may also cause us to:

• issue capital stock that would dilute our current stockholders’ percentage ownership;

• use a substantial portion of our cash resources or incur debt;

• assume liabilities;

• record goodwill or incur amortization expenses related to certain intangible assets; and

• incur large and immediate write-offs and other related expenses.

Any of these factors could prevent us from realizing the anticipated benefits of an acquisition, and our failure to realize these benefits could adversely affect our business. In addition, we may not be successful in identifying future acquisition opportunities or in consummating any acquisitions that we may pursue on favorable terms, if at all. Any transactions that we complete may impair stockholder value or otherwise adversely affect our business and the market price of our stock. Failure to manage and successfully integrate acquisitions could materially harm our financial condition and operating results.

32

The cyclical nature of the semiconductor industry, which has historically demonstrated significant and prolonged downturns, could impact our operating results, financial condition and cash flows.

The semiconductor industry has historically exhibited cyclical behavior which at various times has included significant downturns in customer demand. These conditions have caused significant variations in product orders and production capacity utilization, as well as price erosion. Because a significant portion of our expenses is fixed in the near term or is incurred in advance of anticipated sales, we may not be able to decrease our expenses rapidly enough to offset any unanticipated shortfall in revenues. If this situation were to occur, it could adversely affect our operating results, cash flow and financial condition.

Our business may be adversely impacted if our end customers cannot obtain sufficient supplies of other components in their products to meet their production projections and target quantities.

Our power management products are used by our customers in conjunction with a number of other components such as digital integrated circuits, baseband processors, microcontrollers and digital signal processors. If for any reason our customers incur a shortage of any component, their ability to produce the forecasted quantity of their end product or model may be adversely affected and our product sales would decline until such shortage is remedied. Such a situation could harm our operating results, cash flow and financial condition.

A failure of our information systems would adversely impact our ability to process orders for and manufacture products.

We operate a multinational business enterprise with manufacturing, administration and sales groups located in Asia, Europe and the United States. These disparate groups are connected by a virtual private network-based enterprise resource planning system, where daily manufacturing operations and order entry functions rely on maintaining a reliable network among locations. Any failure of our computer network or our enterprise resource planning system would impede our ability to schedule orders, monitor production work in process and ship and bill our finished goods to our customers.

A failure to maintain our international structure may adversely affect our tax rate, financial condition and operating results.

During 2005, we realigned certain areas of our operations in connection with the implementation of an international structure. This realignment required us to transfer certain functions previously handled in our Sunnyvale, California headquarters to offices in foreign jurisdictions, primarily Macau. If we fail to maintain our realigned operations, our operating results may be adversely affected. Additionally, our international structure results in an increased volume of transactions and accounting for those transactions may require us to increase our headcount either domestically or internationally. A failure to process those transactions in an accurate and timely manner could be indicative of a material weakness in our internal controls over financial reporting. Our international structure requires that we understand complex tax laws and regulations in various domestic and international jurisdictions. If we are unable to comply with domestic and international tax laws, our tax rate and our financial condition may be adversely impacted. Further, the domestic and international tax laws governing our structure are subject to change, which could adversely affect our operations and financial results.

Changes in effective tax rates or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.

Our future effective tax rates could be adversely affected by earnings being lower than anticipated in countries where we have lower statutory rates and higher than anticipated in countries where we have higher statutory rates, by changes in the valuation of our deferred tax assets and liabilities, or by changes in tax laws, regulations, accounting principles or interpretations thereof. Further, as a result of certain ongoing employment and capital investment commitments made by us, our income in certain countries is subject to reduced tax rates, and in some cases is wholly exempt from tax. Our failure to meet such commitments could adversely impact our effective tax rate. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our operating results and financial condition.

33

The requirement that we expense employee stock options has significantly reduced our net income and will continue to do so in future periods.

We adopted SFAS 123(R) effective January 1, 2006, which requires the measurement of all share-based payments to employees, including grants of employee stock options, using a fair-value-based method and the recording of such expense in our consolidated statements of operations. As a result of adopting SFAS 123(R), we now have additional stock-based compensation expense associated with grants after April 4, 2005, the date of our initial filing of our registration statement in connection with our initial public offering, based on the grant date fair value. The ultimate amount of future stock-based compensation expense will depend upon the number of grants, the estimated grant date fair value, which depends upon significant assumptions including stock volatility and estimated term, the assumed forfeiture rate and the requisite service period for future grants. This expense has had a significant impact on our results of operations since 2006. We have recorded approximately $1.7 million and $1.5 million of stock-based compensation expense under SFAS 123(R) for the quarters ended June 30, 2007 and 2006, respectively. We believe that this will continue to have a significant impact on our future operating results.

If we fail to maintain an effective system of internal controls, we may not be able to accurately report our financial results, our business could be harmed and our stock price could decline.

Effective internal controls are critical for us to provide reliable and accurate financial reports and prevent fraud. We have devoted significant resources in order to comply with the internal control over financial reporting requirements under the Sarbanes-Oxley Act of 2002.

Our compliance with the Sarbanes-Oxley Act of 2002 in the future will depend on the effectiveness of our financial reporting, integrity of the data, and effective controls across our operating subsidiaries. Part of our growth strategy has been, and may continue to be, growth through the acquisition of complementary businesses. We expect the controls over the mergers and acquisitions and integration processes to be complex and thus increase difficulty and costs in managing and enforcing the controls over the acquired businesses. Any failure to implement the required controls on the acquired businesses could cause it to fail to meet our financial reporting requirements. Inferior internal controls could also cause investors to lose confidence in our reported financial information and could have a negative impact on the trading price of our stock. In addition, because of the uncertainty of the recent SEC and Public Company Accounting Oversight Board proposals regarding Section 404, we cannot be certain that the controls we designed, implemented and maintained are effective to meet the new and future measures.
