FSQ0565R, FSQ0765R — Green-Mode Farichild Power Switch (FPS™) for Quasi-Resonant Operation October 2007 FSQ0565R, FSQ0765R Green-Mode Fairchild Power Switch (FPS™) for Quasi-Resonant Operation – Low EMI and High Efficiency Features Optimized for Quasi-Resonant Converter (QRC) Low EMI through Variable Frequency Control and AVS
Description
A Quasi-Resonant Converter (QRC) 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 quasi-resonant operation and Alternating Valley Switching (AVS). The PWM controller includes an integrated fixed-frequency oscillator, Under-Voltage Lockout (UVLO), LeadingEdge Blanking (LEB), optimized gate driver, internal softstart, temperature-compensated precise current sources for a loop compensation, and self-protection circuitry [ … ]
