June 10, 2004

PROXY STATEMENT

The Board of Directors (“Board”) of Semtech Corporation (the “Company”) 200 Flynn Road, Camarillo, California, 93012-8790, furnishes this Proxy Statement in connection with its solicitation of proxies to be voted at the Annual Meeting of Stockholders to be held at the Hyatt Westlake Plaza, 880 S. Westlake Boulevard, Westlake Village, California 91361 (101 Freeway, exit Westlake Boulevard) on Thursday, June 10, 2004 at 1:00 p.m., Pacific Daylight Savings Time, or at any adjournments or postponements thereof. The Company is paying the cost of this solicitation of proxies. The mailing of proxy materials will commence on or about May 5, 2004.

Here is some important information regarding the Annual Meeting and this Proxy Statement:

What am I voting on?

(1) To elect eight directors to hold office until the next Annual Meeting or until their successors are duly elected and qualified. The nominees are

Mr. John D. Poe	Mr. Jason L. Carlson
Mr. Rockell N. Hankin	Mr. James T. Lindstrom
Mr. Glen M. Antle	Gen. John L. Piotrowski USAF (Ret.)
Mr. James P. Burra	Mr. James T. Schraith

(2) To ratify the appointment of Ernst & Young LLP as the independent public accountant for the Company.

Who is entitled to vote?

Stockholders as of the close of business on April 23, 2004 (the “Record Date”) are entitled to vote and are entitled to attend the Annual Meeting. Each stockholder is entitled to one vote for each share of common stock held on the Record Date. Stockholders do not have the right to cumulate votes.

How do I vote?

Indicate your voting preferences on the proxy, sign and date it, and return it in the prepaid envelope. If you return your signed proxy but do not indicate your voting preferences, we will vote FOR the two proposals on your behalf. You have the right to revoke your proxy any time before the meeting by (1) notifying the Company’s Secretary, or (2) returning a later-dated proxy. You may also revoke your proxy by voting in person at the meeting.

What does it mean if I get more than one proxy card?

It means you hold shares registered in more than one account. You must return all proxies to ensure that all your shares are voted.

Who will count the vote?

Mellon Investor Services will tabulate the votes and act as inspector of election.

What constitutes a quorum?

A majority of the outstanding shares present or represented by proxy constitutes a quorum for the Annual Meeting. As of the Record Date, 75,381,537 shares of Semtech Corporation common stock were issued and outstanding. Proxies submitted by brokers that do not indicate a vote for some of the proposals because the holders do not have discretionary voting authority and have not received instructions from the beneficial owners on how to vote on those proposals are called “broker non-votes.” Abstentions and “broker non-votes” are each included in the determination of shares present and voting, with each tabulated separately. Abstentions are counted in tabulations of votes cast on proposals presented to the stockholders, whereas broker non-votes are not counted for purposes of determining whether a proposal has been approved.

2

How many votes are needed for approval of each item?

Directors will be elected by a plurality of the votes cast in person or by proxy at the Annual Meeting, meaning the eight nominees receiving the most votes will be elected directors. A stockholder may not cumulate his or her votes for individual directors. The selection of our independent public accountant will be ratified if a majority of the votes present in person or by proxy are voted in favor of the proposal.

What percentages of stock do the directors and officers own?

Together, they own approximately 9.1% of Semtech common stock as of January 25, 2004. See the section titled “Beneficial Ownership of Securities”.

Who are the largest principal shareholders?

The chart in the section titled “Beneficial Ownership of Securities” sets forth each owner of greater than 5% of the Company’s common stock.

How do I receive additional copies of these proxy materials or obtain a copy of the Company’s Bylaws?

Any stockholder desiring additional proxy materials or a copy of the Company’s Bylaws should contact Suzanna Fabos, Secretary, Semtech Corporation at (805) 498-2111 or 200 Flynn Road, Camarillo, California 93012-8790.

• for ratification of the appointment of Ernst & Young LLP as the Company’s independent public accountant for fiscal year 2005.

INFORMATION ABOUT THE BOARD OF DIRECTORS

Independence

The Board is comprised of a majority of independent Directors. The Board has determined that Directors Antle, Burra, Hankin, Lindstrom, Piotrowski and Schraith are independent under the Marketplace Rules of The NASDAQ Stock Market, Inc. (“NASDAQ”), as well as in the assessment of the Board. Directors Poe and Carlson are or were recently employed by the Company and thus do not meet the independence standards.

Code of Conduct

The Board has adopted a written Code of Conduct that applies to the Directors and everyone in the Company, including the Chief Executive Officer and Chief Financial Officer. The Code of Conduct is the Company’s written code of ethics under NASDAQ and Securities and Exchange Commission (“SEC”) rules and has been filed with the SEC as Exhibit 14 to the Company’s Form 10-K for fiscal year 2004.

Meetings

During the Company’s last fiscal year, the Board of Directors held five regular meetings and three special meetings. During such fiscal year, each of the incumbent Directors attended 75% or more of the sum of the number of such meetings plus the number of meetings of the committees of which such person was a member. The average attendance by current directors was over 95%. During fiscal year 2004, the Board of Directors also conducted some business by resolution without meeting, as provided in the Company’s Bylaws. It is expected that the Board will meet on a regular basis during the ensuing year and the Board has adopted a resolution calling for the independent directors to meet quarterly in executive sessions to be held following regularly scheduled Board meetings.

Attendance at Annual Meeting

All of the nominees for Director at the Annual Meeting of Stockholders held in June 2003 were in attendance. The following policy has been adopted by the Board: The Company considers attendance at the Annual Meeting of Stockholders to be a fundamental duty of each Board member, as it provides an opportunity for shareholders to communicate directly with the Directors about issues affecting the Company. Therefore, it is the policy of Semtech Corporation that Board members attend the Annual Meeting of Stockholders unless health, family or other important personal matters prohibit such attendance.

Committees

The Board has a standing Compensation Committee and a standing Audit Committee. The Board does not have a standing nominating committee. Nominating functions will be handled by an ad hoc Nominating Committee.

Compensation Committee

The Compensation Committee, which met four times during fiscal year 2004, is comprised of Directors Antle, Piotrowski and Schraith. Director Schraith serves as chairman. The Board has determined that each member of the Compensation Committee is independent as defined by NASDAQ rules. The Compensation Committee determines the compensation of the Chief Executive Officer and all other executive officers, in accordance with NASDAQ rules. Its responsibilities also include monitoring the performance of the Company’s key executives; reviewing the Company’s management succession plan; assessing the Company’s overall compensation and benefit structure; and administering the Company’s stock option plans and certain of its benefit plans.

During fiscal year 2004 and until committee responsibilities were realigned in the first quarter of fiscal year 2005, the Compensation Committee was also responsible for making recommendations to the Board of Directors regarding the size and composition of the Board and the various Board committees, reviewing the qualifications of potential director candidates and making recommendations to the Board with respect to nominees to be submitted to the stockholders or to be elected by the Board to fill vacancies and newly created directorships, and recommending assignment of specific directors to specific committees. In the future, these functions will be carried out by an ad hoc Nominating Committee, as discussed below.

Audit Committee

The Audit Committee is comprised of Directors Hankin, Burra, and Lindstrom, with Director Hankin serving as chairman. The Board has determined that each member of the Audit Committee is independent as defined by NASDAQ and SEC rules. The Board has also determined that Directors Hankin, Burra, and Lindstrom are financially sophisticated as defined by NASDAQ rules and audit committee financial experts as defined by SEC rules.

The Audit Committee met five times during fiscal year 2004. The Audit Committee’s responsibilities include appointing and overseeing the engagement of the Company’s independent accountant; reviewing the scope and results of the audit conducted

6

by the independent accountant; reviewing the Company’s significant accounting policies; reviewing the independent accountant’s assessment of the adequacy of the Company’s internal controls; and reviewing and approving the financial statements to be included in the Company’s Annual Report on Form 10-K. The Audit Committee meets periodically with the Company’s independent accountant without the presence of Company management. The Audit Committee was recently designated by the Board to serve as the Qualified Legal Compliance Committee, within the meaning of Section 205 of the SECs Standards of Professional Conduct for Attorneys. The current responsibilities of the Audit Committee are more fully described in its written charter, the last revision of which was adopted by the Board in April 2004. The revised charter is included as Appendix A to this Proxy Statement. The Committee has also adopted a policy regarding pre-approval of services to be provided by the Company’s independent public accountant, which is described under the heading “Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services “ on page 20, and procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, which are described under the heading “Contacting the Board of Directors” on page 8.

Ad Hoc Nominating Committee

During the first quarter of fiscal year 2005, the Board realigned committee responsibilities. Nominating functions will now be carried out by an ad hoc Nominating Committee rather than by the Compensation Committee. When needed, the Nominating Committee will be appointed by the Chairman of the Board from among the independent directors. The work of the Nominating Committee generally is not spread throughout the year and selecting its members closer to the time the work begins, rather than almost a year in advance, will facilitate the functioning of the Committee by ensuring all members have ample time to devote to the task. In lieu of a charter, the Board has adopted resolutions addressing Nominating Committee matters. These resolutions are attached to this Proxy Statement as Appendix B.

Board of Directors Compensation

In 1998, the directors who are not also employees of our Company were converted from a cash compensation program to 100% equity based compensation. On July 15, 1998 each non-employee director received a stock option grant that vested pro-rata over five years. This option grant was to compensate the non-employee directors for their service over the five-year period of July 15, 1998 to July 15, 2003 and was granted in lieu of cash compensation. This plan was developed by an independent consulting firm, and was established to align the interests of the Board with those of stockholders, to reduce the expense associated with directors’ compensation and to attract and retain high quality directors.

In continuation of this policy, on December 5, 2002, a stock option grant was made to each then non-employee director in lieu of a cash retainer and meeting fees for the period July 15, 2003 through July 15, 2008. The number of options was computed by multiplying the forgone cash compensation over the five-year period by four (multiplier), and then dividing that amount by the Company’s stock price on the date of grant, to compute the number of options to be granted. The multiplier was set to recognize the relative risk of taking stock options, compared to cash compensation. As a result, Director Hankin, Vice-Chairman of the Board, was granted 46,047 stock options, and Directors Antle, Burra, Lindstrom, Piotrowski and Schraith were each granted 30,698 stock options. A cash retainer of $12,500 was paid to each of the Directors who first joined the Board on December 5, 2002 (Directors Antle, Lindstrom and Piotrowski) for services from their date of election through July 14, 2003, the beginning of the vesting period for the options described above. Twenty percent of these options vest each year, but the annual vesting will not occur, and that portion of the award will be forfeited, if a Director does not attended three of the four most recent regularly scheduled meetings for that year, with certain exceptions. Director Poe’s status changed to that of a non-employee Director in October 2003. In lieu of cash retainers and meeting fees for the period from October 6, 2003 through July 15, 2008, Director Poe was granted an option for 45,960 shares of the Company’s stock, based on the same formula used for the December 2002 grants to other non-employee directors and taking into consideration the leadership role of the Chairman. The vesting schedule and other terms and conditions of his options are the same as those applicable to the options granted to the other non-employee directors for service through July 15, 2008.

Each January 1 and July 1, each non-employee director also receives a stock option grant to purchase 5,000 shares at the market price as of the date of grant. These options, and all options awarded to non-employees for service as a director during fiscal year 2004, are governed by the terms of the Company’s Long Term Stock Incentive Plan, which was approved by the stockholders in June 1998 and is on file with the SEC.

Non-employee directors are also reimbursed for expenses related to Board membership and are covered by the travel accident policy maintained by the Company for officers and employees. Directors who are Company employees are not paid fees or additional compensation for attending Board or committee meetings. Mr. Carlson is currently the only employee on the Board.

In addition to the compensation provided to outside directors generally, the following arrangements were made with Mr. Poe upon his termination of employment and change to non-employee Director status in October 2003:

He is entitled to continue participation in Company-sponsored medical and dental plans on an individual or family basis, as he elects, until he reaches the age of sixty-five. The Company is not obligated to provide any insurance not available to Company

7

employees generally and the allocation of premiums between the Company and Mr. Poe will be calculated in the same manner as for Company employees generally. Mr. Poe will pay his allocated portion of the premiums on an annual basis.

Should Mr. Poe leave the Board in good standing prior to the final vesting date for employee stock options awarded to him prior to October 6, 2003, and if he so requests, the Company will employ him on a part time basis from the date he ceases to be a Director until September 21, 2007 on such terms and conditions as the Compensation Committee may then establish.

The Company will continue to provide to Mr. Poe, without charge, a computer, cell phone and similar items for use on Company business.

Compensation Committee Interlocks and Insider Participation

Directors Antle, Piotrowski and Schraith currently comprise the Compensation Committee. No member of the Compensation Committee was, during fiscal year 2004, an officer or employee of the Company or any of its subsidiaries; or was formerly an officer of the Company or any of its subsidiaries. During fiscal year 2004, no executive officer of the Company served as an executive officer, director or member of the compensation committee (or other board committee performing equivalent functions, or in the absence of such committee, the entire board of directors) of another entity, one of whose executive officers served as a member of the Compensation Committee or as a director of the Company.

CONTACTING THE BOARD OF DIRECTORS

Nomination of Candidates for the Board of Directors

The Nominating Committee will consider recommendations for director nominations submitted by stockholders entitled to vote generally in the election of directors. Submissions for the 2005 Annual Meeting must be received no later than December 31, 2004; must otherwise be made in accordance with the procedures set forth in Section D of Appendix B to this Proxy Statement; and must include all information specified in that section. The Nominating Committee will only consider candidates who satisfy the Company’s minimum qualifications for director, as set forth in Appendix B, including that directors represent the interests of all stockholders. One of the factors that will be taken into account in considering a stockholder recommendation is the size and duration of the recommending stockholder’s ownership interest in the Company and whether the stockholder intends to continue holding that interest through the annual meeting date. Stockholders should be aware that it is the general policy of the Company to re-nominate qualified incumbent directors and that, absent special circumstances, the Nominating Committee will not consider other candidates when a qualified incumbent consents to stand for re-election. See Appendix B for more information on the nominating process.

Shareholder Proposals

The Company must receive stockholder proposals for the 2005 Annual Meeting no later than January 5, 2005 in order to be considered for inclusion in the Company’s proxy materials. Furthermore, proposals by stockholders submitted outside the process of Rule 14a-8 under the Securities Exchange Act of 1934 will be considered untimely and ineligible to properly come before the Company’s 2005 Annual Meeting if such proposal is not received by the Company by March 21, 2005. Stockholder proposals must be submitted in writing to the Company’s Secretary at the Company’s headquarters at 200 Flynn Road, Camarillo, California 93012-8790.

Accounting Matters

The Audit Committee has established procedures for the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters (“Accounting Matters”). Employees with concerns regarding Accounting Matters may report their concerns in writing to the Chief Financial Officer, Chief Executive Officer or the Corporate Counsel. Employees may also report concerns regarding Accounting Matters anonymously directly to the Audit Committee via the confidential reporting system maintained by the Company. Non-employee complaints regarding Accounting Matters may be reported by writing to the Audit Committee c/o the Secretary at the Company’s headquarters at 200 Flynn Road, Camarillo, California 93012-8790.

Other Business Matters

A process for security holders to send communications to the Board, including procedures for collecting, organizing, and otherwise handling such communications, has been adopted by a majority of the independent members of the Board. Security holders may communicate with the Board, or any Committee or Director, about Company business by writing to such party in care of the Company Secretary at the Company’s headquarters at 200 Flynn Road, Camarillo, California, 93012-8790. Security holders are encouraged to include evidence of their holdings with their communications.

REPORT OF THE COMPENSATION COMMITTEE

Compensation Policies for Executive Officers

In the Compensation Committee’s role of overseeing the Company’s compensation and benefit policies, it is responsible for reviewing and approving the nature and amount of compensation paid to the Company’s executive officers, administering and making awards under the Company’s stock option programs, and approving and evaluating performance-based goals related to the incentive compensation of certain executive officers. The Compensation Committee consists entirely of Directors who are “independent directors” under NASDAQ rules, “non-employee directors” as defined in SEC Rule 16b-3, and “outside directors” as defined in Section 162(m) of the Internal Revenue Code.

The Compensation Committee believes that a fair and motivating compensation program plays a critical role in the performance of the Company and, to that end, it reviews the program on an ongoing basis to evaluate its continued effectiveness. The Compensation Committee’s policies are designed to

• ensure compensation programs are effective in attracting and retaining key executives responsible for the success of the Company;

• align total compensation for senior management with both annual and long-term corporate performance; and

• align the interests of our executive officers with the interests of our stockholders.

The Company’s overall financial performance is a significant consideration in establishing total compensation for the executive officers. The Compensation Committee believes that at the executive officer level, a greater proportion of total compensation should consist of variable, performance-based components, such as bonuses, which can increase or decrease to reflect changes in corporate and individual performance. These incentive compensation programs are intended to reinforce management’s commitment to enhancing profitability and stockholder value.

The Compensation Committee also evaluates the Company’s total compensation package in light of those of other analog and mixed-signal semiconductor companies of comparable size. Data from the competitive marketplace are employed to ensure that the Company’s executive compensation program as a whole is within the broad middle range of comparative pay for similar sized companies. The Compensation Committee does not target a specific position in the range of comparative data for each individual

16

or for each component of compensation. When deemed appropriate by the Compensation Committee, independent compensation and benefits consultants are retained to assist in evaluating the Company’s compensation programs. This provides additional insight and assurance that the programs are reasonable and appropriate to the Company’s objectives. Individual compensation for each executive officer is established by considering the comparative data and other relevant factors such as level of responsibility, prior experience, and the Compensation Committee’s subjective judgment as to the individual’s contribution.

Compensation Components

The Company’s executive compensation program has the following principal components.

• Base Salary. An individual’s base salary is determined after reviewing industry and peer group comparisons. We also consider the individual’s total compensation package, scope of responsibilities, years of experience, and past and expected future contributions to the Company’s success. In general, salaries are set based on median salaries for similarly situated executives of similar sized companies in the high technology industry.

• Bonus. Executive officers and other key employees may earn annual cash bonuses based on performance. Targeted bonuses, and thus the amount of total compensation at risk, increase with the level of responsibility and range from 10% of base salary up to 80% of base salary for the most senior officers. These bonus awards provide a means to link the Company’s achievement of measurable items such as orders, revenue, and net income with the individual’s attainment of personal and departmental goals and overall performance. Goals are established and performance is evaluated quarterly. Executive officers may elect early in the fiscal year to receive up to 50% of any bonus that may be earned in that fiscal year in the form of stock options. If a bonus is awarded (in the early part of the next fiscal year), the number of options granted in lieu of bonus is calculated by multiplying the forgone cash bonus by four and dividing the result by the market price on the date of grant. The calculated number of options is priced at the market price on the date of grant, is immediately vested, and is subject to the terms and conditions of the applicable stock option plan and award agreement.

• Stock Options. Stock options are granted periodically to executives and other employees to serve as a retention incentive and to directly link a portion of employee compensation to stockholders’ interest by providing motivation to maximize stockholder value. Beginning in fiscal year 2003, the Company expanded its stock option program to encompass virtually all of its full time employees. In granting options, the Compensation Committee takes into account the number of shares available for grant, the outstanding options held by the individual, and the individual’s relative job scope and performance and contribution to the Company’s success. Most stock options granted since fiscal year 2001 vest in equal annual installments over four years, beginning on the first anniversary of the grant. In prior years, the Committee awarded some key employees options that vest based on performance. No performance-based options were granted to individuals who were executive officers at the time of the grant.

• Deferred Compensation. As a means of providing a retention incentive to executives and other key employees, the Company established a new deferred compensation plan effective in January 2004. This plan was designed with the assistance of an outside compensation consulting firm and is called the “Semtech Executive Compensation Plan”. Under the plan, executives selected by the Committee, including named executive officers, may defer up to 100% of their salary, as defined by the plan. As currently implemented, the Company matches dollar for dollar up to the first 20% of employee contributions for the Chief Executive Officer, Chief Financial Officer, and Chief Operating Officer positions; up to the first 15% for certain key employees; and up to the first 10% for other participants. The plan also permits the Company to make other contributions on a discretionary basis. Each company contribution vests separately, which maximizes the plan’s usefulness as a retention incentive. Vesting occurs in equal annual increments over four years.

The Company terminated the previous arrangement under which variable universal life insurance policies and/or annuities were purchased for executives selected by the Compensation Committee, including some named executive officers. No further employer contributions will be made under the arrangement, all amounts contributed by the Company were vested, and all Company connections to the insurance products were severed.

Chief Executive Officer Compensation

As a matter of Committee policy and in accordance with NASDAQ rules, the Chief Executive Officer is not present during Committee votes or deliberations concerning his compensation.

Mr. Poe

During fiscal year 2004, Mr. Poe served as the Company’s CEO through October 6, 2003. In accordance with the compensation philosophy stated above and the Company’s results, Mr. Poe’s base salary during fiscal year 2004 was $375,000, which was the same base salary he earned during fiscal years 2002 and 2003. His base salary was designed to be competitive with base salaries paid to other chief executive officers of corporations with similar revenues and scope of operations.

17

The Compensation Committee approves performance goals and objectives for the CEO each quarter and also assesses his accomplishment of previously established objectives on a quarterly basis. Company performance is a significant portion of each quarter’s objectives, with the remaining elements reflecting matters most important to the Company. This process is the basis for determining the amount of any bonus awarded to the CEO. During fiscal year 2004, Mr. Poe received a bonus of $120,000 based upon his performance during fiscal year 2003. This bonus was paid $90,000 in cash, with the remaining $30,000 paid in the form of 8,996 stock options. This bonus was 40% of Mr. Poe’s targeted bonus for fiscal year 2003. For fiscal year 2004, Mr. Poe earned a bonus of $61,968, which was 30% of his targeted pro-rated bonus. This bonus was paid to Mr. Poe in cash during the first quarter of fiscal year 2005.

During the portion of fiscal year 2004 Mr. Poe served as Chief Executive Officer, the Compensation Committee granted him 60,000 stock options with an exercise price at fair market value as of the date of the grant. During fiscal year 2004, the Company contributed $113,288 on Mr. Poe’s behalf to the old executive life insurance program.

The compensation arrangements made with Mr. Poe when he retired and became non-employee Chairman of the Board are discussed under the heading “Board of Directors Compensation” on page 7.

The base salary and stock options received by Mr. Carlson during fiscal year 2004 were determined through pre-employment negotiations with him. The agreements reached with Mr. Carlson were approved by the Compensation Committee. As an inducement for Mr. Carlson to join Semtech in November 2002, the Company agreed that should he be promoted to Chief Executive Officer, his annual salary would be increased by $50,000 to $350,000 and he would be granted options to purchase 250,000 shares of the Company’s common stock. These compensation commitments were put into effect when Mr. Carlson was elected to the CEO position in October 2003.

As a further inducement for Mr. Carlson to join Semtech, the Company agreed that should his services be terminated by the Board, he will be granted a severance allowance equal to six months salary and benefits continuation upon signing of a non-compete agreement and a full release of all claims and obligations. Vesting of stock options would cease as of the last day that services are actively provided to the Company.

As noted above, the Compensation Committee both approves performance goals and objectives for the CEO and evaluates his accomplishment of previously established objectives on a quarterly basis. During fiscal year 2004, Mr. Carlson received a bonus of $21,426 based upon his performance during the portion of fiscal year 2003 that he was with the Company. This bonus was 36% of his targeted pro-rated bonus for fiscal year 2003. For fiscal year 2004, Mr. Carlson earned a bonus of $100,000, which was 36% of target. This bonus was paid to Mr. Carlson in cash during the first quarter of fiscal year 2005.

During fiscal year 2004, the Company contributed $5,400 to Semtech Executive Compensation Plan on Mr. Carlson’s behalf.

Tax Matters

For federal and most state income tax purposes, no more than $1 million of compensation paid to the chief executive officer and the four other most highly paid executive officers may be deducted in a taxable year unless the compensation is commission or performance based. Stock options awarded under the Company’s stock option plans are intended to meet the requirements for deductible performance-based compensation. The Compensation Committee awarded inducement options, within the meaning of NASDAQ rules, to Mr. Carlson in November 2002 and to our new Chief Operating Officer in April 2004. Tax deductions for compensation related to these inducement options may be limited in future years, depending on a number of factors, including the timing and amount of option exercises and IRS rules then in existence. The Compensation Committee believes the benefit of using inducement options as a recruitment incentive to attract key executives outweighs the potential loss of tax deductions that may or may not occur in future years.

INDEPENDENT ACCOUNTANT FEES

	Fiscal Year 2004		Fiscal Year 2003
Fees paid to Ernst & Young LLP for:
Audit Services	$	449,700	$	375,000	*
Audit-Related Services		0	$	3,000
Tax Services	$	5,000		0
All Other Services		0		0
Total	$	454,700	$	378,000

In the table above, certain amounts for fiscal year 2003 have been reclassified to conform to the fiscal year 2004 presentation. Since the May 2003 effective date of the SEC rules regarding approval, each new engagement of Ernst & Young LLP was approved in advance by the Audit Committee, and none of those engagements made use of the de minimis exception contained in the rules. The Audit Committee has considered the nature and scope of the non-audit services provided by Ernst & Young and has concluded that Ernst & Young’s performance of these services is compatible with the auditor’s independence.

Audit Services. The amounts shown for this category are fees paid to Ernst & Young LLP for the audit of the Company’s financial statements for the fiscal years ended January 25, 2004 and January 26, 2003, respectively, and for reviews of the financial statements included in the Company’s Form 10-Qs for those fiscal years.

Audit-Related Services. In fiscal year 2003 the Company paid $3,000 to Ernst & Young LLP for assistance with various accounting issues.

Tax Services. In fiscal year 2004, the Company paid $5,000 to Ernst & Young LLP for assistance with filing German tax returns for the Company’s German subsidiary.

* In addition, the Company paid $22,000 to its prior independent public accountant, Arthur Andersen LLP, for review of the financial statements included in the Company’s Form 10-Q for the first quarter of fiscal year 2003.

POLICY ON AUDIT COMMITTEE PRE-APPROVAL OF AUDIT AND PERMISSIBLE NON-AUDIT SERVICES

The Audit Committee is responsible for appointing, compensating, and overseeing the work of the independent auditor. In recognition of this responsibility, the Audit Committee has established a policy regarding pre-approval of all audit and permissible non-audit services provided by the independent auditor. The policy calls for an annual review and pre-approval, up to specified dollar limits, of certain types of services that may be provided by the independent auditor without obtaining specific pre-approval from the Audit Committee. During the year, circumstances may arise when it may become necessary to engage the independent auditor for additional services not contemplated in the original pre-approval categories. In those instances, specific pre-approval must be obtained. The Audit Committee has delegated to its Chairman the authority to address certain requests for pre-approval of services between meetings of the Audit Committee. The Chairman must report his pre-approval decisions to the Audit Committee at its next scheduled meeting.

Change of Independent Public Accountant in 2002

On June 18, 2002, the Company dismissed Arthur Andersen LLP (“Andersen”) and engaged Ernst & Young LLP to serve as the Company’s independent auditors for the fiscal year 2003. These decisions were authorized and directed by the Company’s Board of Directors upon recommendation of its Audit Committee.

Andersen’s reports on the Company’s consolidated financial statements for each of the fiscal years ended January 27, 2002 and January 28, 2001 did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended January 27, 2002 and January 28, 2001, there were no disagreements with Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Andersen’s satisfaction, would have caused it to make reference to the subject matter in connection with its reports; and there were no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K.

During the fiscal years ended January 27, 2002 and January 28, 2001 and through June 18, 2002, the Company did not consult Ernst & Young LLP with respect to the application of accounting principles to a specified transaction, either completed or proposed, the type of audit opinion that might be rendered on our consolidated financial statements, or any other matter or reportable event as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

The Company provided Andersen a copy of the foregoing disclosures, and Andersen provided a letter, dated June 24, 2002, stating that it has found no basis for disagreement with such statements. This letter is included in the Company’s current report on Form 8-K, filed with the SEC on June 25, 2002, reporting the change in Certifying Accountant.

APPROVAL OF APPOINTMENT

OF INDEPENDENT PUBLIC ACCOUNTANT

(Proposal No. 2)

The Audit Committee has appointed Ernst & Young LLP as the Company’s independent public accountant for fiscal year 2005. Ernst & Young has served as the Company’s independent public accountant since June 2002, replacing Arthur Andersen LLP. Ratification of the independent accountant is not required by the Company’s Bylaws or applicable law, but has historically been submitted to stockholders as a matter of good corporate practice. No determination has been made as to what action the Board would take if stockholders do not ratify the appointment.

Representatives of Ernst & Young LLP are expected to attend the Annual Meeting. They will have the opportunity to make a statement, if they so desire, and respond to appropriate questions from stockholders.

OTHER MATTERS

The management of the Company knows of no other matters that may properly be, or which are likely to be, brought before the meeting. However, if any other matters are properly brought before the meeting, the persons named in the proxy or their substitutes will have discretion to vote in accordance with their best judgment on such matters.

Appendix A

SEMTECH CORPORATION

AUDIT COMMITTEE CHARTER

A. Introduction

Semtech Corporation’s executive management is primarily responsible for the completeness and accuracy of its financial reporting and the adequacy of its internal financial and operating controls. Its Board of Directors (“Board”) has responsibility to oversee management’s exercise of these responsibilities. To assist the Board, the Company has established, through its Bylaws, an Audit Committee (“Committee”) whose authority and responsibilities are described by this Charter.

B. Purpose

This Charter is created in order to define the Committee’s objectives, the range of its authority, the scope of its activities and its duties and responsibilities. It is intended to give Committee members, management, and the Auditor a clear understanding of their respective roles. For purposes of this Charter, the “Auditor” is any registered independent public accountant retained by the Company for the purpose of preparing or issuing an audit report on the financial statements of the Company or performing other audit, review or attest services for the Company.

The purpose of the Committee is to assist the Board in overseeing:

• the accounting and financial reporting processes of the Company;

• the integrity of the Company’s financial statements and systems of internal controls and disclosure controls;

• the audits of the Company’s financial statements;

• the appointment, compensation, retention and work of the Auditor;

• the Company’s financial risk;

• the Company’s compliance with legal and regulatory requirements; and

• the Company’s Code of Conduct.

The Committee shall also serve as the Company’s Qualified Legal Compliance Committee (“QLCC”) within the meaning of Part 205 of the Rules of the Securities and Exchange Commission (“SEC”) dealing with Standards of Professional Conduct for Attorneys.

In carrying out its responsibilities, the Committee will maintain and facilitate free and open communication among directors, the Auditor and the financial and executive management of the Company.

The Committee will annually review and reassess the adequacy of the Committee’s Charter.

C. Size, Composition and Term of Appointment

1. The Committee is a committee of the Board and shall be made up entirely of outside directors who are independent of management, as defined by the relevant SEC and National Association of Securities Dealers (“NASD”) rules, and who have not participated in the preparation of the financial statements of the Company or any current subsidiary.

2. The Committee shall consist of no fewer than three directors, each of whom shall be able to read and understand fundamental financial statements, including the Company’s balance sheet, income statement and cash flow statement. At least one member of the Committee shall be an “audit committee financial expert” as defined by the SEC.

3. The Board shall annually appoint the Committee’s Chair and members and as part of that process shall determine whether each member is independent and which members are audit committee financial experts.

4. Notwithstanding any designation as an audit committee financial expert, each member of the Committee is expected to contribute significantly to the work of the Committee. Moreover, designation as an audit committee financial expert will not increase the duties, obligations or liability of the designee as compared to the duties, obligations and liability imposed on the designee as a member of the Committee and of the Board.

A-1

D. Meetings

1. The Committee will meet on a quarterly basis and special meetings may be called when circumstances require.

2. Minutes of Committee meetings will be prepared and distributed to Committee members and approved at subsequent meetings. Final minutes of all Committee meetings shall be sent to the Secretary of the Company for safekeeping with the Company’s records.

3. The Committee will be governed by the same rules regarding meetings, actions without meetings, notice, waiver of notice, and quorum and voting requirements that are applicable to the Board.

F. Outside Advisors/Funding

1. The Committee has the authority to engage independent counsel and other advisors as it deems necessary to carry out its duties. The Company shall provide for the appropriate funding, as determined by the Committee, for payment of (i) compensation to any such counsel and other advisors engaged by the Committee, (ii) compensation to the Auditor for the purpose of rendering or issuing an audit report or performing other audit, review, or attest services, and (iii) ordinary administrative expenses necessary or appropriate in carrying out its duties.

2. Any communications between the Committee and legal counsel in the course of obtaining legal advice will be considered privileged communications of the Company, and the Committee will take all necessary steps to preserve the privileged nature of those communications.

G. Independent Public Accountant (Auditor)

1. The Auditor will report and be accountable directly to the Committee.

2. The Committee will be directly responsible for the appointment, compensation, retention and oversight of the work of the Auditor. Before appointing the Auditor, the Committee will confirm that the Auditor has received or is subject to an external quality review by an independent public accountant (“peer review”) sufficient to meet NASD requirements. In addition, the Committee may propose that the engagement of the Auditor be submitted for shareholder approval or ratification in the proxy statement.

Appendix B

SEMTECH CORPORATION

NOMINATING COMMITTEE MATTERS

A. The Board of Directors (“Board”) of Semtech Corporation has by resolution determined that it will have an ad hoc Nominating Committee (“Committee”) in lieu of a standing Nominating Committee and that the establishment and operation of any such Committee shall be governed by the following:

1. The Chairman of the Board shall appoint a Committee from time to time as needed to accomplish the following objectives:

• identify and evaluate individuals qualified to become members of the Board, and

• select, or recommend that the Board select, the director nominees for the next annual meeting of shareholders.

2. The Committee will be composed entirely of Directors who satisfy the definition of “independent” under the listing standards of The Nasdaq Stock Market (Nasdaq).

3. The Committee shall have the authority to delegate any of its responsibilities to subcommittees as the Committee may deem appropriate.

4. The Committee shall meet when convened by the Chairman of the Board and thereafter as often as its members deem necessary to perform the Committee’s responsibilities. The Chairman of the Board shall disband the Committee when its work has been completed.

5. The Committee will be governed by the same rules regarding meetings, actions without meetings, notice, waiver of notice, and quorum and voting requirements that are applicable to the Board. The Committee is authorized to adopt its own rules of procedure not inconsistent with any provision of this Charter, the Bylaws of the Corporation, or the laws of the State of Delaware.

6. The Committee will have the authority, to the extent it deems necessary or appropriate, to retain a search firm to assist in identifying director candidates. The Committee shall have sole authority to retain and terminate any such search firm, including sole authority to approve the firm’s fees and other retention terms. The Committee shall also have authority, to the extent it deems necessary or appropriate, to retain other advisors. The Company will provide for appropriate funding, as determined by the Committee, for payment of compensation to any search firm or other advisors employed by the Committee.

7. The Committee will make reports to the Board and will propose any necessary action to the Board.

8. The Committee will approve director nominations to be presented for shareholder approval at the annual meeting and to fill any vacancies.

B. The Board has also determined by resolution that any ad hoc Nominating Committee that is established will observe the following procedures in identifying and evaluating candidates for the Board:

1. The Committee shall consider that continuing service of qualified incumbents promotes stability and continuity, contributing to the Board’s ability to work as a collective body, while giving the Company the benefit of the familiarity and insight into the Company’s affairs that its directors have accumulated during their tenure. Accordingly, the process of the Committee for identifying nominees shall reflect the Company’s practice of re-nominating incumbent directors who (a) continue to satisfy the criteria for membership on the Board, (b) the Committee believes to continue to make worthwhile contributions to the Board and (c) consent to continue to serve on the Board.

2. The Committee will evaluate the qualifications and performance of the incumbent directors that desire to continue their service by:

• considering if the director continues to satisfy the minimum qualifications for director candidates;

• assessing the performance of the director during the preceding term; and

• determining whether there exist any special, countervailing considerations against re-nomination of the director.

3. If the Committee determines that an incumbent director consenting to re-nomination continues to be qualified and has satisfactorily performed his or her duties as director during the preceding term and the Committee finds no reason, including considerations relating to the composition and functional needs of the Board as a whole, why the incumbent should not be re-nominated, then the Committee will propose the incumbent director for re-election.

B-1

4. The Committee will identify and evaluate new candidates for election to the Board where there is no qualified and available incumbent, including for the purpose of filling vacancies arising by reason of the resignation, retirement, removal, death or disability of an incumbent director or a decision of the directors to expand the size of the Board.

5. The Committee will solicit recommendations for nominees from persons that the Committee believes are likely to be familiar with qualified candidates. These persons may include members of the Board, including members of the Committee, and management of the Company. The Committee may also engage a professional search firm to assist in identifying qualified candidates.

6. As to each recommended candidate that the Committee believes merits consideration, the Committee will:

• assemble information on the background and qualifications of the candidate, including information concerning the candidate required to be disclosed in the Company’s proxy statement under the rules of the SEC and any relationship between the candidate and the person or persons recommending the candidate;

• determine if the candidate satisfies the minimum qualifications;

• determine if the candidate possesses any of the specific qualities or skills that must be possessed by one or more members of the Board by law or listing regulation;

• consider the contribution that the candidate can be expected to make to the overall functioning of the Board; and

• consider the extent to which the membership of the candidate on the Board will promote diversity among the directors.

7. It is appropriate for the Committee, in its discretion, to solicit the views of the Chief Executive Officer, other members of the Company’s senior management, and other members of the Board regarding the qualifications and suitability of candidates.

8. In its discretion, the Committee may designate one or more of its members (or the entire Committee) to interview any proposed candidate.

9. Based on all available information and relevant considerations, the Committee will select a candidate who in its view is most suited for membership on the Board.

10. In making its selection, the Committee will evaluate candidates proposed by shareholders under criteria similar to the evaluation of other candidates, except that the Committee may consider, as one of the factors in its evaluation of shareholder recommended nominees, the size and duration of the interest of the recommending shareholder or shareholder group in the equity of the Company and whether the recommending shareholder intends to continue holding that interest at least through the time of the annual meeting.

11. The Committee shall maintain appropriate records regarding its process of identifying and evaluating candidates for election to the Board.

C. The Board has determined by resolution that any ad hoc Nominating Committee that is established will use the following criteria in identifying and evaluating candidates for the Board, as the Board believes that its members must posses certain basic personal and professional qualities in order to properly discharge their fiduciary duties to shareholders, provide effective oversight of the management of the Company, and monitor the Company’s adherence to principles of sound corporate governance:

All persons nominated to serve as a director of the Company should possess the minimum qualifications described below. These are only threshold criteria, and the Committee should also consider the contributions that a candidate can be expected to make to the collective functioning of the Board based upon the totality of the candidate’s credentials, experience and expertise, the composition of the Board at the time, and other relevant circumstances.

1. Integrity. All candidates must be individuals of personal integrity and ethical character.

2. Absence of Conflicts of Interest. Candidates should not have any interests that would materially impair his or her ability to (i) exercise independent judgment, or (ii) otherwise discharge the fiduciary duties owed as a director to the Company and its shareholders.

3. Fair and Equal Representation. Candidates must be able to represent fairly and equally all shareholders of the Company without favoring or advancing any particular shareholder or other constituency of the Company.

4. Achievement. Candidates must have demonstrated achievement in one or more fields of business, professional, governmental, communal, scientific or educational endeavor.

B-2

5. Oversight. Candidates are expected to have sound judgment, borne of management or policy-making experience (which may be as an advisor or consultant), that demonstrates an ability to function effectively in an oversight role.

6. Business Understanding. Candidates must have a general appreciation regarding major issues facing public companies of a size and operational scope similar to the Company, including regulatory obligations and governance concerns of a public issuer; strategic business planning; competition in a global economy; and basic concepts of corporate finance.

7. Available Time. Candidates must be prepared to devote adequate time to the Board and its committees. It is expected that each candidate will be available to attend all meetings of the Board and any committees on which the candidate will serve, as well as the Company’s annual meeting of shareholders.

8. Limited Exceptions. Under exceptional and limited circumstances, the Committee may approve the candidacy of a nominee who does not satisfy all of these requirements if it believes the service of such nominee is in the best interests of the Company and its shareholders.

9. Additional Qualifications. In approving candidates for election as director, the Committee will also assure that:

• at least a majority of the directors serving at any time on the Board are independent, as defined by the relevant Securities and Exchange Commission (“SEC”) and National Association of Securities Dealers (“NASD”) rules;

• at least three of the directors satisfy the financial literacy requirements required for service on the audit committee under NASD rules;

• at least one of the directors qualifies as an audit committee financial expert under SEC rules;

• at least some of the independent directors have experience as senior executives of a public or substantial private company; and

• at least some of the independent directors have general familiarity with an industry or industries in which the Company conducts a substantial portion of its business or in related industries.

10. Diversity. The Committee will seek to promote an appropriate diversity on the Board of professional background, experience, expertise, perspective, age, gender, and ethnicity.

D. The Board has determined by resolution that any ad hoc Nominating Committee that is established will fully and fairly consider, in the same manner in which it considers any other candidate for Board membership, any candidate submitted by a shareholder that adheres to the following procedure, provided however, that in evaluating shareholder-recommended nominees the Committee may consider the size and duration of the recommending shareholder’s equity interest in the Company and whether the recommending shareholder intends to continue holding that interest at least through the time of the annual meeting:

1. Manner and Address for Submission. All shareholder nominating recommendations must be in writing, addressed to the Company in care of the Secretary at the Company’s headquarters. Submissions must be made by certified mail or commercial courier service (Federal Express, for example). Hand delivered or emailed submissions will not be considered.

2. Information Concerning the Recommending Shareholders. A nominating recommendation must be accompanied by the following information concerning each recommending shareholder:

• The name and address, including telephone number, of the recommending shareholder;

• The number of the Company’s shares owned by the recommending shareholder and the time period for which such shares have been held;

• If the recommending shareholder is not a shareholder of record, a statement from the record holder of the shares verifying the holdings of the shareholder and a statement from the recommending shareholder of the length of time that the shares have been held; and
