SUNNYVALE, Calif., June 28, 2013 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today released AON6970 and AON6978, high power density 30V PairFET™ devices, both in an asymmetric dual (high-side and low-side integrated MOSFETs) DFN5x6 package. The devices are ideally suited for high performance DC/DC solutions for networking point-of-load (POL) converters, servers, advanced notebooks, desktops, all-in-one PCs as well as isolated DC/DC converters in telecom and industrial applications.

Developed with AlphaMOS™ technology, the new PairFETs feature ultra-low Rds(on) and gate charge to operate at a higher switching frequency – producing highly-efficient solutions in a compact DFN5x6 package. The PairFET's asymmetric configuration improves performance by allowing the size of the low-side MOSFET to be increased for lowest conduction loss. The combination of AlphaMOS low voltage technology and the effective package configuration of the PairFET devices allow the AON6970 to offer on-resistance as low as 2.3mO max at Vgs=4.5V on the low side.

"AOS's new PairFET MOSFETs help simplify power designs and save space in high efficiency synchronous buck single and multi-phase DC/DC converters by providing an optimized combination of high-side and low-side MOSFETs in a single compact package," said Yalcin Bulut, Vice President of Discrete Product Lines at AOS.

The AON6970 and AON6978 devices are 100% Rg and UIS tested, and are RoHS and Halogen-Free compliant.
