Alpha and Omega Semiconductor Introduces a Highly Versatile DrMOS Power Module

High power and optimal system level efficiency solution for high-end computing and graphic applications

SUNNYVALE, Calif., Feb. 28, 2017 (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 introduced AOZ5038QI, the highly versatile latest generation of power modules. The AOZ5038QI integrates a dual gate driver and two optimized MOSFETs in a 31-pin 5mm x 5mm QFN package to produce a high-power and high-efficiency power stage for synchronous step-down applications. The new AOZ5038QI enables high power density-voltage regulator solutions ideal for CPU and GPU power regulation in notebook PCs, servers, and graphic cards. The standard 5mm x 5mm QFN package is optimally designed to provide maximum power density and minimize parasitic inductance for minimal EMI signature.
