Photo Release -- Alpha and Omega Semiconductor Offers New Solutions for the Ultra-Portable Market

April 3, 2012

SUNNYVALE, Calif., April 3, 2012 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors for the wireless portable market, today introduced a series of new solutions in a DFN 2mm x 2mm package. This broad portfolio of new products offers exceptional performance while enabling affordable form factor solutions used in hand held applications.

The ultra small package is optimized for portable wireless solutions such as in tablet PCs, eReaders, smart phones, digital cameras, MP3 players, and ultrabook computers. The ultra low on-resistance of these MOSFETs reduces conduction losses which translate into lower power consumption and longer battery life. The compact footprint and ultra-thin 0.6 mm profile of the DFN2x2 power package enables more efficient solutions in space constrained applications.

AON2410, AON2409, AON2408, AON2407, and AON2406 are the best-in-class 20V and 30V devices on the market today in a DFN2x2 package and are used for load and battery switches in portable applications.

AON2403, AON2405, and AON2406 provide ultra low on-resistance values down to guaranteed spec at 1.5V rating helping the designers to drive their circuit with lower supply voltage, which in turn lowers the power consumption and improves battery life.

"These new DFN2x2 power package solutions which utilize AlphaMOS™ Low Voltage technology offer exceptional performance and make affordable form factor solutions for the wireless mobile market a possibility," said Peter Wilson, Director of Low Voltage MOSFETs at AOS.
