The VIPER22ADIP-E is a fixed frequency off line converter in 8 pin DIP package. This off line converter combines dedicated current mode PWM controller with high voltage power MOSFET on same silicon chip. The internal control circuit offers large input voltage range on VDD pin which accommodates changes in auxiliary supply voltage. This feature is well adapted to battery charger adapter configurations.
