STCH02

STCH02 Offline PWM controller for ultra-low standby adapters SO-8 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  Intelligent frequency jitter for EMI suppression  SO-8 package Applications  AC-DC chargers for smartphones, tablets, camcorders and other handheld equipment  AC/DC adapters for STB, notebooks and auxiliary power supplies Datasheet - preliminary data Description 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 choice to build a high efficiency and ultra-low standby consumption power supply, with high overall and excellent dynamic performances.
