STCH03 - Offline PWM controller

Features

  • Advanced power management for ultra-low standby power consumption (under 10 mW at 230 VAC).
  • Fully integrated primary side constant current output regulation (CC).
  • 650 V embedded HV start-up circuit with zero power consumption.
  • Quasi-resonant (QR) zero-voltage-switching (ZVS) operation.
  • Accurate and adjustable output OVP with options auto-restart (STCH03) or latched (STCH03L) after fault.
  • Output undervoltage protection (UVP) with auto-restart.
