Description
The FSDM0465RS is an integrated Pulse-Width Modulator (PWM) and SenseFET specifically designed for high-performance offline Switch Mode Power Supplies (SMPS) with minimal external components. The device is an integrated, high-voltage, power switching regulator that combines an avalanche rugged SenseFET with a current mode PWM control block.
