Quasi resonant controllers designed for ultralow standby power supplies

Stocked by Mouser, the STMicroelectronics STCH02 PWM Quasi resonant controllers are designed for ultralow standby power supplies. The controllers have built-in HV start-up cells with zero power consumption. These ICs are the best choice to build a high efficiency and ultra-low standby consumption power supplies. The controllers have fully integrated blocks for primary side constant current output regulation. They have advanced power management with high overall and excellent dynamic performances. Typical applications include AC-DC chargers for smartphones, tablets, camcorders and other handheld equipment; AC/DC adapters for STB, notebooks and auxiliary power supplies.
