Single inductor DC-DC converter with bipolar outputs using charge pump

This paper describes a bipolar outputs DC-DC converter that uses a single inductor for size and cost reduction. We propose timing diagram for a charge pump circuit in the negative voltage generation part, and present its configuration, operation principle and simulation results. We also show that em...

Zusammenfassung:This paper describes a bipolar outputs DC-DC converter that uses a single inductor for size and cost reduction. We propose timing diagram for a charge pump circuit in the negative voltage generation part, 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.
