The VIPer12A combines a dedicated current mode
PWM controller with a high voltage Power
MOSFET on the same silicon chip. 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 V DD 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.
