FSQ311 General 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-Width Modulation (PWM) controller andSenseFET specifically designed for valley switchingoperation with minimal external components. The PWMcontroller includes an integrated fixed-frequencyoscillator, Under-Voltage Lockout, Leading EdgeBlanking (LEB), optimized gate driver, internal soft-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. This deviceprovides a basic platform that is well suited for cost-effectivedesigns of valley switching fly-back converters.
