ST VIPer22A-E VIPer22ADIP-E VIPer22AS-E handbook
The VIPer22A-E series combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip. These devices are designed for low power OFF-line SMPS applications such as battery charger adapters and standby power supplies for TVs or monitors. The integrated control circuit offers a wide range of Vpp voltage (9 V to 38 V) and includes overtemperature, overcurrent, and overvoltage protection with auto-restart.
