Acquisitions [Abstract]
Business Combination Disclosure	Acquisitions Triune Systems, L.L.C On March 4, 2015 the Company acquired Triune Systems, L.L.C., a privately-held supplier of wireless charging and power management platforms targeted at, among other things, high and low power, high efficiency applications. Under the terms of the purchase agreement the Company acquired all of the outstanding equity interest in Triune for a guaranteed minimum purchase price of $45.0 million consisting of $35.0 million in cash paid at closing, with an additional cash consideration of $10.0 million to be paid six months after the transaction closing date and additional contingent consideration subject to achieving certain future financial goals (“Triune Earn-out”). Under the terms of the Triune Earn-out, up to $70.0 million of consideration will be paid over three years if certain revenue targets are achieved in each of the fiscal years 2016 through 2018. An additional payment of up to $16.0 million will be paid after fiscal year 2018 if certain cumulative revenue and operating income targets are achieved. The fair value of the Triune Earn-out is estimated to be $16.7 million, of which $16.2 million is presented under "Other liabilities" in the condensed consolidated balance sheet as of April 26, 2015. The remaining portion of the Triune Earn-out that is dependent on continued employment is accounted for as compensation expense as the requisite services are provided (see Note 13). During the quarter ended April 26, 2015, the Company borrowed $35.0 million under its revolving line of credit in connection with this acquisition (see Note 10 for discussion regarding Credit Facilities). The acquisition is accounted for under the acquisition method of accounting in accordance with the FASB’s Accounting Standards Codification (“ASC”) Topic 805, Business Combinations. Total acquisition consideration will be allocated to the acquired tangible and intangible assets and assumed liabilities of Triune based on their respective estimated fair values as of the acquisition date. Acquisition-related transaction costs are not included as a component of consideration transferred, but are accounted for as an expense in the period in which the costs are incurred. Any excess of the acquisition consideration over the fair value of the assets acquired and liabilities assumed will be allocated to goodwill. The goodwill resulted from expected synergies from the transaction, including complementary products that will enhance the Company’s overall product portfolio, and opportunities within new markets. The Company is currently in the process of evaluating the fair value of the acquired tangible and intangible assets and goodwill assumed in the business combination. As of April 26, 2015, based on the Company’s preliminary estimates, $10.0 million of the total acquisition consideration has been allocated to core technologies, $2.0 million to customer relationships and $49.4 million to goodwill. The remaining balance was allocated to identifiable tangible assets and assumed liabilities. The Company expects that all such goodwill will be deductible for tax purposes. The purchase price allocation for the Triune acquisition is preliminary and will be finalized upon collection of information regarding the fair values of assets and liabilities acquired. The primary areas of the preliminary purchase price allocation that are not yet finalized include fair values of certain tangible assets and liabilities acquired, identifiable intangible assets, certain legal matters, income and non-income based taxes, residual goodwill, the allocation of goodwill to reporting units, and its impact on segment reporting. The Company expects to complete the purchase price allocation for its acquisition of Triune in the third quarter of fiscal 2016.

On January 13, 2015, the Company paid $4.9 million to acquire select assets from EnVerv, a privately-held supplier of power line communications (“PLC”) and Smart Grid solutions targeted at advanced metering infrastructure, home energy management systems and IoT applications. The Company has concluded that the acquired assets constituted a business and accordingly accounted for this transaction as a business combination.
