Claim:
1. A method of operating a voltage regulator comprising a source voltage rail and a plurality of output voltage rails, the method comprising: converting a source voltage on the source voltage rail to an output voltage on each output voltage rail of the plurality of output voltage rails; selecting an output voltage rail from the plurality of output voltage rails; comparing the output voltage on the selected output voltage rail to a reference voltage for the selected output voltage rail; increasing, by the voltage regulator, the output voltage on the selected output voltage rail when the output voltage of the selected output voltage rail is less than the reference voltage of the selected output voltage rail, wherein a first frequency at which an output voltage rail is selected is dependent upon the rate at which the voltage regulator has previously increased the output voltage on the selected output voltage rail; and selecting a next output voltage rail from the plurality of output voltage rails and repeating the comparing and the increasing steps.
