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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
