Low Power OFF-Line SMPS Primary Switcher  
Features  
Fixed 60kHZ Switching Frequency  
9V to 38V Wide Range V Voltage  
DD  
Current Mode Control  
Auxiliary Undervoltage Lockout with Hysteresis  
High Voltage Start-up Current Source  
SO-8  
DIP-8  
Overtemperature, Overcurrent and  
Overvoltage Protection with Auto-Restart  
Typical power capability  
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:  
– European (195 - 265 Vac) 8W for SO-8,  
13W for DIP-8  
– European (85 - 265 Vac) 5W for SO-8,  
8W for DIP-8  
– Large input voltage range on the V pin  
DD  
Description  
accommodates changes in auxiliary supply  
voltage. This feature is well adapted to  
battery charger adapter configurations.  
The VIPer12A combines a dedicated current  
mode PWM controller with a high voltage Power  
MOSFET on the same silicon chip.  
– Automatic burst mode in low load condition.  
– Overvoltage protection in HICCUP mode.
