AN-1081 Low-Cost Low-Parts-Count DC/DC Converter With Multiple Outputs (Rev. B)

Texas Instruments

Published Date: 04/23/2013

Description

This application report describes a simple low cost low parts-count multiple output DC/DC converterbased on the LM2596 five terminal step-down switching regulator. The circuit described provides multipleoutput voltages (positive and negative) with good regulation using a step-down converter circuit withflyback windings. It uses only one switching regulator IC.
