Offline PWM quasi resonant controller for ultra-low standby power supplies

Description

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.
