Abstract
A single-inductor multiple-output DC-DC converter includes a first power switch controlled by a first power switch signal and a second power switch controlled by a second power switch signal, connected in series between a positive supply voltage and a negative supply voltage, and interconnected at an input node; a single inductor with a first end connected to the input node; a plurality of output switches, controlled by corresponding output switch signals, connected in parallel with first ends connected to a second end of the inductor, second ends of the output switches, acting as output nodes, providing corresponding output voltages respectively; and a dual mode charge controller coupled to receive an input voltage at the input node, to receive the output voltages, to receive a state flag, and configured to accordingly generate the first and second power switch signals and the output switch signals.
