Alpha and Omega launches PairFET devices
The new MOSFETs will help designers achieve top power density and efficiency for telecoms and advanced computing solutions
Alpha and Omega Semiconductor Limited (AOS) has released the AON6970 and AON6978, high power density 30V PairFET devices.
They both come in an asymmetric dual (high-side and low-side integrated MOSFETs) DFN5 x 6 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 RdsON and gate charge to operate at a higher switching frequency. This results in highly-efficient solutions in a compact DFN5 x 6 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 optimised combination of high-side and low-side MOSFETs in a single compact package," says 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.
Availability
The AON6970 and AON6978 are immediately available in production quantities with a lead-time of 12-14 weeks. The unit price for 1,000 pieces is $1.20 and $0.63, respectively.
Alpha and Omega Semiconductor Limited, or AOS, is a designer and developer of a broad range of power semiconductors. These include power MOSFET, IGBT and power IC products.
