Optimization of a multi-target voltages switched capacitor converter

Abstract

In this paper, an efficient voltage scalable switched capacitor converter (SCC) for 1.1V battery-powered system is presented. The SCC employs a binary resolution technique to step-down the input voltage to a range of voltages, while keeping the efficiency high. An optimization strategy for designing multi-topology SCC is presented to improve the effectiveness of the circuit and to preserve efficiency over large load voltages.
