Abstract:
A control circuit for a variable phase voltage regulator comprises an error amplifier to generate a difference signal based on a difference between a reference voltage and a signal representative of a voltage at an output node of the variable phase voltage regulator. The control circuit also comprises a variable phase compensator to amplify the difference signal to produce a modified difference signal to compensate for effects of varying the number of active phases in the variable phase voltage regulator, wherein the amplification is proportional to a ratio of total number of phases in the variable phase voltage regulator to number of active phases in the variable phase voltage regulator.
