SIC645ALR-T1-GE3

SIC645ALR-T1-GE3 is a VRPower® smart power stage module with integrated high-accuracy current and temperature monitors. It is a smart VRPower® device that integrates 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. This simplify design and increase performance by eliminating the DCR sensing network and associated thermal compensation. Light-load efficiency is supported via a dedicated left control pin. The application includes 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.
