Alpha and Omega Semiconductor Introduces Best-In-Class DrMOS-IV Power Modules

April 21, 2016


SUNNYVALE, Calif., April 21, 2016 (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 AOZ5049, the first of the fourth generation of high efficiency power modules with an EZPair™ package. The AOZ5049 is housed in a 24-pin 3.5mm x 5mm QFN package that integrates a dual gate driver and two enhanced MOSFETs, which together produce a high efficiency DC-DC synchronous buck power stage. The new device enables high power density voltage regulator solutions ideal for Notebook PCs, servers, and graphic cards applications.

The AOZ5049 is an optimized solution with improved efficiency and thermal performance for Intel IMVP8 compatible CPUs, comparing to previous generation. Efficiency has been improved by 2.5 percent at heavy load, and thermal improvement has minimized power device loss — reducing the IC surface temperature by 10 percent.

"The heavy load efficiency of the AOZ5049 is 1 percent higher and the IC surface temperature is almost 10 percent lower than that of the closest competitor," said Kenny Hu, Power IC Product Marketing Manager at AOS.
