Green Mode Fairchild Power Switch (FPS?⩠for Valley Switching Converter

A Valley Switching Converter FSQ0365 FSQ0265 FSQ0165 FSQ321 FSQ311 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. Compared with Discrete MOSFET and PWM Controller solutions, the FSQ-series reduces total cost, component count, size and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform that is well suited for cost- effective designs of valley switching fly-back converters. By Fairchild Semiconductor
