DESCRIPTION

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 VDD 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.
