Abstract: A single inductor multiple output DC-to-DC converter may be configured as a buck-boost converter. The converter may include an inductor, a plurality of switches coupled to the inductor to control energizing and deenergizing phases of the inductor, and a plurality of output rails. Each of the plurality of output rails may include at least one switch, which is configured to connect the output rail to the inductor of the buck-boost converter. Depending on the energizing and deenergizing patterns of the inductor, and the state of the one or more switches, the various output rails may be supplied with a plurality of different output voltages and / or output currents. Any of a plurality of regulating strategies may be utilized to further control the output voltages and / or the output currents.
