STMicroelectronics STCH02TR 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 STCH02TR have fully integrated blocks for primary side constant current output regulation. The controllers have advanced power management with high overall and excellent dynamic performances.
