摘要：

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