INTRODUCTION


The VIPer20 is a full integrated switching device. It replaces the conventional PWM driver circuit, its
associated high voltage Power MOSFET switch and a full set of other passive components, and provide
a high level of performance thanks to its current mode structure and standby operation capability.

1. SCOPE
The VIPer20 is initially designed to be used at the primary side of any off line power supplies in isolated
