STCH02 Datasheet (STMicroelectronics) - Offline PWM controller

STCH02, Offline PWM controller

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

The built-in HV startup cell with zero power consumption, the fully integrated blocks for primary side constant current output regulation and the advanced power management make this IC the best

STCH02 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) o
