60A DrMOS Power Module is 5mm-Square

Alpha and Omega Semiconductor Limited (AOS) 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 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.

“Complement to our small form factor, QFN3.5x5 power stage series, the AOZ5038QI is a new addition to our QFN5x5 standard package footprint series with higher power density for today's high-end computing and graphic applications,” said Peter Cheng, Sr. Director of Power IC Product Line at Alpha and Omega Semiconductor.

Technical highlights include: Input voltage range of 4.5V to 25V; Output current up to 60A; Switching frequency up to 2MHz; Package, 31-pin 5mm x 5mm QFN; and meets IMVP8 standard. The AOZ5038QI is immediately available in production quantities with a lead-time of 12 weeks. The unit price for 1,000 pieces is $1.90.
