FSQ311 Features

FSQ311 Description

A Valley Switching Converter generally shows lower EMIand higher power conversion efficiency than aconventional hard-switched converter with a fixedswitching frequency. The FSQ-series is an integratedPulse-WidthModulation(PWM)controllerandSenseFET specifically designed for valley switchingoperation with minimal external components. The PWMcontrollerincludesanintegratedfixed-frequencyoscillator, under-voltage lockout, Leading-Edge Blanking(LEB),optimizedgatedriver,internalsoft-start,temperature-compensated precise current sources forloop compensation, and self-protection circuitry.Compared with discrete MOSFET and PWM controllersolutions, the FSQ-series reduces total cost, componentcount, size and weight; while simultaneously increasingefficiency, productivity, and system reliability. Thisdevice provides a basic platform for cost-effectivedesigns of valley switching fly-back converters.
