60-A-rated gate driver integrates MOSFET, diode

The IR3550 PowIRstage is a synchronous buck gate driver with an integrated synchronous MOSFET, and a Schottky diode available in a 6 x 6 x 0.9-mm PQFN package. It is a 60-A rated product that targets high-current multiphase buck regulators and simplifies dc/dc converter design for next-generation servers, storage, and communication systems.

The MOSFET device achieves up to a 97% efficiency at 1.2 V, has an input voltage range to 25 V, and output range from 0.25 to 3.3 V, and a switching frequency up to 1.0 MHz. It integrates a current-sense amplifier and features a synchronous diode-emulation that removes the zero-current detection and control burden from the PWM controller. The device is optimized for CPU core-power delivery in server applications and powering GPU and DDR memory designs. (From $2.65 ea/10,000 available now.)
