Abstract
Certain aspects of the present disclosure generally relate to methods and apparatus for operating a switched-mode power supply (SMPS). One example method generally includes selecting a first output of a plurality of outputs of the SMPS based on a power demand associated with each of the plurality of outputs if a voltage at the first output is less than a reference voltage associated with the first output, by selecting as the first output one of the plurality of outputs having the highest power demand, and based on an amount of overcharge associated with the first output if the voltage at the first output is greater than the reference voltage, by selecting as the first output one of the plurality of outputs having the lowest amount of overcharge. The method may also include directing current across an inductive element of the SMPS to the first output based on the selection.
