Photo Release -- Alpha and Omega Semiconductor Features New Ground Exposed Die
Pad Power IC Platform

SUNNYVALE, Calif., Nov. 6, 2012 (GLOBE NEWSWIRE) -- Alpha and Omega
Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global
supplier of a broad range of power semiconductors, today introduced its new
Ground Exposed Die Pad Power IC platform, an innovative packaging technology
capable of exceptional power dissipation. The high performance of this EZBuck™
dc/dc platform is attributed to a combination of IC design, low on-resistance
MOSFET technology, and proprietary exposed ground pad packaging technology.
The new platform enables more thermally efficient dc/dc solutions for
consumer, networking and industrial applications such as LCD TVs, set-top
boxes, cable modems, and power supplies.

The ground exposed die pad platform combines a current-mode step-down
controller IC with integrated high-side and low-side MOSFETs. The vertical
MOSFET structure features outstanding on-resistance performance which allows
more power delivery in a small area, while the exposed ground pad transfers
heat directly to the printed circuit board's ground plane which acts as a
large heat sink. Another benefit of the large ground exposed pad is that it
reduces electromagnetic interference and noise coupling into the system.

The high-side p-channel MOSFET and low-side n-channel MOSFET with integrated
Schottky diode, combined with a bond-wireless packaging technology deliver
best-in-class junction temperature performance for a 30W, 12V to 5V
post-regulating application.

"The integration of the discrete FET technology and the exposed ground pad are
significant features for future EZBuck products, which will offer higher power
density without the added cost," said Daniel Chang, Vice President of Power IC
at AOS.


The first EZBuck products with the new featured platform will be available
within the first quarter of 2013.
