产品概要
描述
The STCH02 is a PWM quasi resonant controller specifically designed for ultra-low standby power supplies.
The built-in HV start-up 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 choice to build a high efficiency and ultra-low standby consumption power supply, with high overall and excellent dynamic performances.
-
All features
- Advanced power management for ultra-low standby power consumptions (under 10 mW at 230 Vac)
