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.
