Patent ID: 7560916

Claim:
A DC-DC voltage converter comprising: at least a first module adapted to receive an input DC voltage and at least one voltage control signal and output an output DC voltage that is a function of the input DC voltage and the at least one voltage control signal; and at least a second module adapted to receive a feedback signal representative of the output DC voltage and utilize digital circuitry to generate the at least one voltage control signal as a function of at least the feedback signal, wherein: the at least a second module comprises a plurality of comparators adapted to compare the feedback signal to a plurality of respective references, and the at least one voltage control signal is based, at least in part, on results of the comparison of the feedback signal to the plurality of respective references; the at least a second module comprises passive components utilized to generate the at least one voltage control signal; the at least a second module comprises switching circuitry coupled to the passive components; wherein the switching circuitry controls generation of the at least one voltage control signal by the passive components; and the at least a second module is adapted to utilize the results of the comparison to control the switching circuitry.
