Tiny Footprint MOSFETs Addressing the Requirements of Ultra-Portable
Applications

SUNNYVALE, Calif., Jan. 14, 2013 (GLOBE NEWSWIRE) -- Alpha and Omega
Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global
supplier of a broad range of power semiconductors and power ICs, today
introduced a family of devices in tiny DFN 1.0mm x 0.6mm and ultra-small DFN
1.6 x 1.6mm packages to meet the small footprint requirements of portable
electronics while still delivering superior performance. These MOSFETs are
optimized for space-constrained portable wireless solutions such as tablet
PCs, eReaders, smart phones, digital cameras, digital media players and
ultrabook computers.

AON1605 and AON1606 are housed in a tiny DFN1.0x0.6 package, while AON1611,
AON1620, and AON1634 are offered in an ultra-small DFN1.6x1.6mm package. The
ultra low on-resistance of these devices reduces conduction losses,
translating into lower power consumption and longer battery life, which is
essential in wireless applications. The compact footprint and ultra-thin (≤
0.55mm) profile of both DFN1.6x1.6 and DFN1.0x0.6 power packages enables more
efficient solutions in space-constrained applications.

"These new tiny DFN power packages utilize AlphaMOS™ technology, which enables
exceptional performance and makes it possible for affordable form factor
solutions for the wireless mobile market," said Peter Wilson, Director of Low
Voltage MOSFETs at AOS.
