DM311A Description
The FSDM311A consists of an integrated Pulse Width Modulator (PWM) and SenseFET, and is specifically designed for high-performance, off-line, Switch-Mode Power Supplies (SMPS) with minimal external ponents. This device is an integrated high-voltage power switching regulator that bines a VDMOS SenseFET with a voltage-mode PWM control block. The integrated PWM controller.
