Description

The VIPer12A-E is a high voltage integrated circuit intended to be used as a primary

side switch on the offline power supply, in a monolithic structure housed in DIP8 or SO-

8 package. It includes a PWM driver, a power MOSFET with 730 V breakdown voltage,

a start-up circuit and several protection circuits. It minimizes the count of external parts ,

reduces the product size and power consumption. This application note describes the

results obtained when the VIPer12A-E is used in mobile charger applications.
