Abstract
A DC/DC voltage conversion system includes a first voltage converter operable to convert a first DC voltage rail to a second DC voltage rail different than the first DC voltage rail, and a second voltage converter operable to convert the second DC voltage rail to a third DC voltage rail lower than the second DC voltage rail. The second voltage converter is a multiphase converter having a plurality of power stages, each power stage providing a phase of the multiphase converter and configured to conduct current. The DC/DC voltage conversion system further comprises a single controller having a first control loop for controlling the first voltage converter and a second control loop for controlling the second voltage converter. The second control loop is a multiphase control loop configured to enable multiphase operation of the second voltage converter.
