SIC645AER-T1-GE3

SIC645AER-T1-GE3 is a VRPower® Smart power stage module with integrated high accuracy current and temperature monitors. It is a high side and low side MOSFET, a high performance driver with integrated bootstrap FET. The SiC645 offers high accuracy current and temperature monitors that can be fed back to the controller and doubler to complete a multiphase DC/DC system. The device features a 3.3V (SiC645A) compatible tri-state PWM input that, working together with multiphase PWM controllers, will provide a robust solution in the event of abnormal operating conditions. Applications include high frequency and high efficiency VRM and VRD, core, graphic, and memory regulators for microprocessors, high density VR for server, networking, and cloud computing, POL DC/DC converters and video gaming consoles.
