FSQ0165 Overview
A Valley Switching Converter generally shows lower EMI and higher power conversion efficiency than a conventional hard−switched converter with a fixed switching frequency. The FSQ−series is an integrated Pulse−Width Modulation (PWM) controller and SENSEFET® specifically designed for valley switching operation with minimal external ponents. The PWM controller includes an integrated fixed−frequency oscillator,...
