FSQ0565RS/RQ — Green-Mode Farichild Power Switch (FPS™) for Quasi-Resonant Operation December 2009 FSQ0565RS/RQ Green-Mode Fairchild Power Switch (FPS™) for Quasi-Resonant Operation - Low EMI and High Efficiency Features ! Optimized for Quasi-Resonant Converters (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).
