Alpha and Omega Introduces Power MOSFETs for Portable Applications

Alpha and Omega Semiconductor Ltd. (AOS) announced that it has set new standards in power density and energy efficiency for power MOSFETs in an ultra-thin (0.8 mm) DFN 3 x 3 package. These devices are implemented on AOS’ proprietary AlphaMOS technology. The combined benefits of longer battery life and a compact form factor make these devices ideal for space-constrained portable applications such as tablet PCs, smart phones, eReaders, notebook computers, digital cameras and portable music players.

The AON7421 and AON7423 are best-in-class 20V P-channel devices with the lowest RDS(ON) in the market of similar package types. AON7421’s on-resistance value at a 2.5V gate voltage is 20% less than the closest competitive device. AON7423 is a low threshold device that operates with a gate drive as low as 1.5V, allowing efficient load switching for low voltage supply rails.

"These AlphaMOS 20V P-channel devices set a new benchmark for power density and performance for portable applications requiring long battery life," said Peter Wilson, Director of Low Voltage MOSFETs. "AOS is committed to continually deliver efficient power solutions to its customers."
