Photo Release -- Alpha And Omega Semiconductor's New 80V And 100V MOSFETs Offer Industry's Lowest On-Resistance In A DFN3.3x3.3 Package

SUNNYVALE, Calif., Dec. 21, 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 announced the release of AON7280 and AON7290, the newest additions to its new 80V and 100V AlphaMOS™ medium voltage portfolio. These new products are well suited for a wide range of applications that include secondary side synchronous rectification in DC/DC and AC/DC converters, POL modules for telecom systems, and POE networking applications.

Built using AOS proprietary AlphaMOS technology, the 80V AON7280 and 100V AON7290 offer ultra-low R DS(ON) that are 27% and 10% better than the leading competitors, respectively. The low on-resistance minimizes conduction losses and allows the device to operate at lower temperatures. This was achieved without compromising switching performance as both devices offer the lowest R DS(ON) * C OSS in the industry. These solutions are packaged in a green DFN3.3x3.3 package, giving circuit designers flexibility in board-space critical applications.

"When constructing efficient power solutions in tight spaces, designers turn to high performance MOSFETs in smaller packages," said Stephen Chang, Sr. Product Marketing Manager at AOS. "AON7280 and AON7290 combine high density AlphaMOS technology with a compact DFN3.3x3.3 package to meet the needs of those designers."

AON7280 Technical Highlights
