Patent ID: 7053713

Claim:
A multi-phase DC-DC converter comprising: a plurality of inductors each having a first terminal coupled to an output capacitor; a plurality of switching circuitries each adapted to couple a second terminal of one of the plurality of inductors to either a source voltage or a current return path based on one of a plurality of control signals; a plurality of current sensing means each adapted to generate a current feedback signal indicative of a current through one of the plurality of inductors; a plurality of current feedback loops each adapted to generate one of the plurality of control signals based on the current feedback signal from one of the plurality of current sensing means and a current loop set-point voltage; and a voltage feedback loop adapted to generate the current loop set-point voltage based on a set-point voltage and a voltage feedback signal indicative of a supply voltage at an output of the multi-phase DC-DC converter; wherein each of the plurality of the current feedback loops operate independently from each other of the plurality of current feedback loops.
