FSQ0365RN Datasheet | Fairchild Semiconductor

Features - Optimized for Quasi-Resonant Converter (QRC) - Low EMI through Variable Frequency Control and 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 Sense FET specifically designed for quasi-resonant operation with minimal external ponents. The PWM controller includes an integrated fixed-frequency oscillator, Under-Voltage Lockout, Leading Edge Blanking (LEB), optimized gate driver, internal soft-start, temperature-pensated precise current sources for loop pensation, and self-protection circuitry. pared with discrete MOSFET and PWM controller solution, the FSQ-series can reduce total cost, ponent 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 quasi-resonant switching flyback converters.
