Application Notes
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.
