WITH HYSTERESIS  
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.  
HIGH VOLTAGE START UP CURRENT

DESCRIPTION  
– Automatic burst mode in low load condition.  
– Overvoltage protection in hiccup mode.  
The VIPer22A combines a dedicated current mode  
PWM controller with a high voltage Power
