Description
The VIPer22A-E combines a dedicated current mode PWM controller with a high voltage power MOSFET on the same silicon chip.
VIPER22ADIP-E chip
Switching power supply (SMPS) 20W intelligent type
High voltage offline converter
Advantages
- Fixed 60 kHz switching frequency9 V to 38 V wide range VpD voltage Current mode control
Auxiliary undervoltage lockout with hysteresis High voltage start-up current source
Overtemperature, overcurrent and overvoltage protection with auto-restart
Application
Typical applications cover off line power supplies for battery charger adapters, standby power
supplies for TV or monitors, auxiliary supplies for motor control, etc. The internal control circuit offers the following benefits:
Large input voltage range on the VpD pin accommodates changes in auxiliary supply voltage.
This feature is well adapted to battery charger adapter configurations.
Automatic burst mode in low load condition. Overvoltage protection in HICCUP mode.
