Stacked MOSFETs save space, achieve 90% efficiency at 25 A

Stacked MOSFETs save space, achieve 90% efficiency at 25 A

The CSD86350Q5D Power Block is a synchronous MOSFET half bridge that achieves >90% efficiency at 25 A and in half the area of competitive power MOSFET devices. It combines two asymmetric NexFET power MOSFETs in an advanced package that delivers high performance in low-voltage synchronous buck half-bridge applications, including servers, desktop and notebook PCs, base stations, switches, routers, and high-current PoL converters.

The MOSFET device can generate up to 40 A of current with a switching frequency of up to 1.5 MHz to reduce solution size and cost. The pinout and grounded lead frame reduces development time and improves overall circuit performance. The device also achieves comparable performance to GaN-based solutions at less cost. The 5 x 6-mm SON dual-MOSFET solution is half the size of the typical two-MOSFET devices in similar packages. The SON package has an exposed grounded pad on the bottom to simplify layout.
