Green Mode Power Switch for Valley Switching Converter - Low EMI and High Efficiency FSQ0365, FSQ0265, FSQ0165, FSQ321 Description 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 components. The PWM controller includes an integrated fixed−frequency oscillator, under−voltage lockout, Leading−Edge Blanking (LEB), optimized gate driver, internal soft−start, temperature−compensated precise current sources for loop compensation, and self−protection circuitry.
