SUNNYVALE, Calif., Sept. 28, 2011 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors, today announced the release of the AOZ1050 and AOZ1051 high efficiency,
simple-to-use synchronous buck regulators. Both AOZ1050 and AOZ1051 are available in a thermally enhanced exposed pad SO-8 package, delivering output current of 2A and 3A, respectively. These new devices are well suited for a variety of consumer electronics applications such as LCD TV, set-top-boxes, DVD players and recorders.

The low on-resistance of internal power MOSFETs in these devices allows higher efficiency and less heat generation. The full load efficiency of AOZ1051 is 7% higher and IC surface temperature is almost 40 degrees C lower than that of the leading competitor. Adjustable soft-start time provides system designers with flexibility for power-up sequencing. Cycle-by-cycle current limiting combined with unique hiccup short-circuit protection ensure reliable operation under any abnormal conditions.
"We continue to expand our EZ Buck product portfolio to provide our customers with higher efficiency and more reliable DC/DC solutions. The AOZ1050 and AOZ1051 are a good example." said Song Qu, Director of Power IC Product Marketing at AOS.
