Application note
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
supply that runs from both European and domestic mains. (90-132 V_ac and 180- 264 V_ac,
47-63 Hz).
