Application note
VIPower: auxiliary BIAS
power supply using VIPer20A-E
Introduction
This application note describes a bias power supply to meet the needs of powering up
Power MOSFETs as well as providing standby power when the main unit is off.
The VIPer20ADIP-E, a part of STMicroelectronics proprietary VIPower (Vertical Intelligent
Power), is a current mode PWM with a 700 V avalanche rugged Power MOSFET. It uses a
fabrication process which allows the integration of analog control circuits with a vertical
power device on the same chip. It can provide an output of 10 W power capability for wide
range input, or 20 W for single input voltage range.
