Alpha and Omega Semiconductor Introduces a High Efficiency DrMOS Power Modules
with Optimized Performance
Versatile synchronous buck power stage feature state-of-the-art technology
SUNNYVALE, Calif., July 28, 2016 – Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer,
developer and global supplier of a broad range of power semiconductors, today announced the release of the AOZ5166QI-01,
the high efficiency power modules which are fully compliant with Intel’s DrMOS specifications. The AOZ5166QI-01 is
housed in a 40-pin 6mm x 6mm QFN package that integrates an optimized dual gate driver and two 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 servers, work stations, graphic cards and high-end desktop PC applications.
The AOZ5166QI-01 utilizes AOS’s proprietary state-of-the-art trench MOSFET and packaging technologies to improve
efficiency and thermal performance over the previous generation solution. Continuous engineering innovations are being
implemented to reduce switching loss and lower power dissipation that ultimately benefit thermal characteristics that lead to
higher current driving capability. The low RDS(ON) of low-side MOSFET combined with the low Qg high-side MOSFET
achieves an optimal balance between switching and conduction losses to increase overall efficiency by 1%.
“To meet ever increasing power density requirements of high-end computing or server applications, we optimized our
DrMOS power module driver performance by reducing switching loss, improving efficiency, and lowering the power
dissipation,” said Kenny Hu, Power IC Product Marketing Manager at AOS.
Pricing and Availability
The AOZ5166QI-01 is available immediately in production quantities. The unit price of 1,000 pieces is $2.15.
