Abstract

This paper introduces a novel single inductor multi-output LED driver. The converter is able to significantly reduce the area of passive components while maintaining high power processing efficiency by dividing power between a switched capacitor (SC) and a buck-boost converter and taking the output differentially from the two outputs. The volume of the SC converter is reduced by operating the buck-boost converter in DCM and increasing the number of SC switching states from two to three. An experimental setup verifies the effectiveness of the design and indicates an efficiency improvement of 2.5% while reducing passive component area by 63% and increasing the operating range compared to conventional commercial products.
