Abstract :
A single-inductor dual-output switching converter was presented in this paper. This converter can be applied to solar-cell portable devices as battery power management system. Considering the limited power supplied by solar cells, two output channels, battery charging and power regulating, were designed for this converter. Controlled by it, the output electric energy could be dynamically distributed between two channels. The state-machine is used to decide the amount of energy delivered to each channel. The converter chip is designed in a 1.5 ¿m BCD (bipolar-CMOS-DMOS) technology. Simulation results showed that all main targets were well achieved.
