Description：

The VIPer22A-E combines a dedicated currentmode PWM controller with a high voltage powerMOSFET on the same silicon chip.Typical applications cover off line power suppliesfor battery charger adapters, standby powersupplies for TV or monitors, auxiliary supplies formotor control, etc. The internal control circuitoffers the following benefits:Large input voltage range on the VDD pinaccommodates changes in auxiliary supplyvoltage. This feature is well adapted to batterycharger adapter configurations.Automatic burst mode in low load condition.Overvoltage protection in HICCUP mode. 

Features：

■ Fixed 60 kHz switching frequency

■ 9 V to 38 V wide range VDD voltage

■ Current mode control

■ Auxiliary undervoltage lockout with hysteresis

■ High voltage start-up current source

■ Overtemperature, overcurrent and overvoltageprotection with auto-restart
