FSCQ0765RTYDTU Product Details

The FSCQ0765RTYDTU is a 650V Integrated Power Switch for 85W offline flyback converters. A Quasi-Resonant Converter (QRC) typically shows lower EMI and higher power conversion efficiency compared to a conventional hard-switched converter with a fixed switching frequency. Therefore, a QRC is well suited for noise-sensitive applications, such as colour TV and audio. Each product in the FSCQ series contains an integrated Pulse Width Modulation (PWM) controller and a SenseFET. This series is specifically designed for quasi-resonant off-line Switch Mode Power Supplies (SMPS) 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.


  • Optimized for Quasi-Resonant Converter (QRC)
  • Advanced burst-mode operation for under 1W standby power consumption
  • Pulse-by-pulse current limit
  • Overload protection (OLP) - Auto restart
  • Overvoltage protection (OVP) - Auto restart
  • Abnormal Over-current Protection (AOCP) - Latch
  • Internal thermal shutdown (TSD) - Latch
  • Under-voltage lockout (UVLO) with hysteresis
  • Low start-up current of 25µA (typical)
  • Internal high voltage SenseFET
  • Built-in soft-start (20ms)
  • Extended quasi-resonant switching
