Lowest RDS(ON) * COSS Figure of Merit in the Market Enables Higher Efficiency Solutions
SUNNYVALE, Calif., Feb. 7, 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 AON6270 and AON6280, the flagship devices in its new 75V and 80V AlphaMOS (aMOS™) medium voltage portfolios. The new product expands AOS' medium voltage MOSFET portfolio and enhances its solutions for high performance power supplies. AON6270 and AON6280 are well suited for a wide range of applications that are pushing the limits of efficiency such as secondary side synchronous rectification in DC/DC and AC/DC converters, primary side switching in telecom and industrial DC/DC converters, POL modules for telecom systems, motor drives, UPS, and industrial automation tools.

Power supply designers can now improve efficiencies even further through the lower conduction and switching losses made possible by AON6270 and AON6280. These new devices deliver the best figure-of-merit for RDS(ON) * COSS, which is 34% and 29% better than the current leading competitors, respectively. The low output capacitances in combination with low Qg reduce MOSFET switching losses. These devices are available in the compact size DFN5x6 green package and are 100% Rg and UIS tested.
"High efficiency power designs require strong performance for MOSFETs in both switching and conduction modes." said Stephen Chang, Sr. Product Marketing Manager at AOS. "AON6270 and AON6280 deliver not only very low RDS(ON), but also provide optimal COSS to help designers meet energy efficiency standards and regulations."
