VIPower: 108 W power supply using VIPer100A-E

Introduction
The VIPer100A-E is designed to deliver 100 W for the upper voltage range or 50 W for
universal input. This application note describes a power supply that delivers over 100 W for
both voltage ranges using a voltage doubler in the front end. The VIPer100A-E combines a
state-of-the-art PWM circuit along with an optimized 700 V avalanche rugged Vertical Power
MOSFET. It is part of STMicroelectronics’ proprietary VIPower, (Vertical Intell
