Description

The FSL126MR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for high performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL126MR includes integrated high-voltage power switching regulators that combine an avalanche-rugged SenseFET with a current-mode PWM control block.
