FSCQ1265RT - Green Mode Fairchild Power Switch

Datasheet Summary

Description

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 color TV and audio.

Features

  • Optimized for Quasi-Resonant Converter (QRC).
  • Advanced Burst-Mode Operation for under 1 W Standby Power Consumption.
  • Pulse-by-Pulse Current Limit.
  • Overload Protection (OLP).
  • Auto Restart.
  • Over-Voltage Protection (OVP).
  • Auto Restart.
  • Abnormal Over-Current Protection (AOCP).
  • Latch.
  • Internal Thermal Shutdown (TSD).
  • Latch.
  • Under-Voltage Lockout (UVLO) with Hysteresis.
  • Low Startup Current (Typical: 25 μA).
  • Internal.
