STCH02 - Offline PWM controller

General Description

The STCH02 is a PWM quasi resonant controller specifically designed for ultra-low standby power supplies.

Key Features

  • Advanced power management for ultra-low standby power consumptions (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.
  • Automatic self-supply.
  • Accurate and adjustable output OVP with autorestart after fault.
  • Input voltage feedforward compensation for mains-independent CC regulation.
  • Intell.
