VIPer22A-E
VIPer22ADIP-E, VIPer22AS-E
Low power OFF-line SMPS primary switcher
Features
■ Fixed 60 kHz switching frequency
■ 9 V to 38 V wide range V
DD
voltage
■ Current mode control
■ Auxiliary undervoltage lockout with hysteresis
■ High voltage start-up current source
■ Overtemperature, overcurrent and overvoltage
protection with auto-restart
Description
The VIPer22A-E 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.

1.1 Maximum ratings
Stressing the device above the rating listed in the “absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
