Single Inductor DC-DC Converter with Independent Bipolar Outputs Using Charge Pump

Abstract:

Article Preview

This paper describes a bipolar output DC-DC converter that uses a single inductor for size andcost reduction. We propose a timing diagram for a charge pump circuit which generates the negative outputvoltage, and present its con guration, operation principle and simulation results. We also show that employingpseudo-continuous conduction mode improves cross-regulation between the two outputs.
