Family of single-inductor multi-output DC-DC converters

This paper presents the family of the single-inductor multi-output DC-DC converters. Conventional transformer-based multi-output DC-DC converters are proposed to provide multiple output voltages, which, however, have the drawbacks of high cost and large volume. Therefore, the single-inductor multi-output three-terminal configuration is developed in order to reduce the component count and cost for multi-output DC-DC converters, including the boost, buck, buck-boost, and flyback DC-DC converters. In this paper, the boost-type single-inductor dual-output DC-DC converter is introduced and analyzed. Furthermore, the family of the single-inductor multi-output DC-DC converters is presented.
