This application note presents a reference design for non-isolated flyback converter based on VIPer12AS monolithic device. The circuit can be used to produce multiple outputs, non isolated positive or negative voltage. It is dedicated for building an auxiliary power supply based on the VIPer12AS monolithic device.
This document presents a reference board design for a non-isolated flyback converter using the VIPer12AS monolithic device. The circuit is designed to produce multiple outputs, either positive or negative, without isolation between the input and output, simplifying transformer design and production costs.
The application note details the circuit description, operating conditions, bill of materials, transformer design parameters, and PCB layout for four different variants of the power supply. It includes schematic diagrams, layout hints, and measured output regulation characteristics.
