FSDM311 Overview
The FSDM311 is an integrated Pulse Width Modulator (PWM) and Sense FET specially designed for high performance off-line Switch Mode Power Supplies (SMPS) with minimal external ponents. This device is a monolithic high voltage power switching regulator which bines an VDMOS Sense FET with a voltage mode PWM control block. The integrated PWM controller.
