Single Inductor Multi Output DC-DC Converter Design with Hythterisis Control

Abstract This paper describes application of the hysteresis control to the single-inductor dual-output (SIDO) power supply circuit to realize high performance, low cost and small size power supply circuits. The SIDOs can realize small number of inductors (hence small size and low cost) in the system where multiple power supplies are required, but their performance is not very good if conventional SIDO control methods are used. We show with simulation and experiment that the hysteresis control can realize high performance SIDO converters.
