Green-Mode Fairchild Power Switch (FPSTM) for Quasi-Resonant Operation
FSQ0365/0265/0165/321 — Green Mode Fairchild Power Switch (FPS™) for Valley Switching Converter August 2011 FSQ0365, FSQ0265, FSQ0165, FSQ321 Green Mode Fairchild Power Switch (FPS™) for Valley Switching Converter – Low EMI and High Efficiency Features Description A Valley Switching Converter generally shows lower EMI Optimized for Valley Switching Converter (VSC) and higher power conversion efficiency than a conventional hard-switched converter with a fixed Low EMI through Variable Frequency Control and switching frequency. The FSQ-series is an integrated Inherent Frequency Modulation Pulse-Width Modulation (PWM) controller and SenseFET specifically designed for valley switching High Efficiency through Minimum Voltage Switching operation with minimal external components. The PWM Narrow Frequency Variation Range Over Wide Load controller includes an integrated fixed-frequency and Input Voltage Variation oscillator, under-voltage lockout, Leading-Edge Blanking (LEB), optimized gate driver, internal soft-start, Advanced Burst-Mode Operation for Low Standby temperature-compensated precise current sources for Power Consumption loop compensation, and self-protection circuitry. Pulse-by-Pulse Current Limit Compared with discrete MOSFET and PWM controller solutions, the FSQ-series reduces total cost, component Protection Functions: Overload Protection (OLP), count, size and weight; while simultaneously increasing Over-Voltage Protection (OVP), Abnormal Over- efficiency, productivity, and system reliability. This Current Protection (AOCP), Internal Thermal device provides a basic platform for cost-effective Shutdown (TSD) designs of valley switching fly-back converters.
