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 Intelligent Power). It

uses a fabrication process, which allows the integration of analog control circuits with

vertical power device on the same chip.

This document covers the implementation and results for achieving 18 V at 6 A power

47-63 Hz).
