Photo Release -- Alpha & Omega Semiconductor Introduces PairFET(TM) High Density Power Stage Products

SUNNYVALE, Calif., April 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, announced today the release of high power density 25V and 30V PairFET™ products in both DFN 5x6 and DFN 3.3x3.3 package (integrated High-Side and Low-Side MOSFETs in one package). This new product family provides compact and efficient DC-DC solutions in notebook PCs, desktop PCs, all-in-one PCs, graphic cards, servers, and networking point-of-load (POL) converters.

The flagship product of the PairFET family is AON6924 which delivers up to 30A of output current from a single DFN 5x6 power package. The AON6924 replaces two DFN 5x6 MOSFETs with a single package, which saves more than 50% board space and simplifies PCB layout. 

"The AON6924 PairFET offers significant advantages over existing discrete solutions by shrinking solution size and by increasing system power efficiency. This enables design engineers to meet their design objectives of delivering high power density DC-DC synchronous buck converter solutions," said Peter Wilson, Director of Low Voltage MOSFETs at AOS.

Technical Highlights

  • High power efficiency in DFN 5x6 asymmetric dual power package
  • Ultra low RDS(ON) 1.6 mOhms (max) at VGS = 10V for low-side MOSFET with integrated Schottky diode
  • Switching optimized 5.2 mOhms max at VGS = 10V for high-side MOSFET
