Regulator Circuit With Multiple Levels

A method for regulating power supplied to a plurality of loads, the method comprising:

• supplying power to the plurality of loads via a plurality of stages of voltage regulators connected in series to a power source;
• determining one of the plurality of stages drawing a highest load current to power its load, the determined one of the plurality of stages being identified as a master stage and the remaining ones of the plurality of stages being identified as slaved stages;
• and
• for each of the plurality of stages:
• calculating a difference between the highest load current and the current drawn by the stage to power its load;
• and
• causing a current to bypass the voltage regulator in the stage, the bypass current corresponding to the calculated difference;
• whereby a total current drawn by each of the stages is equal, the total current of each stage corresponding to a sum of the current drawn by the stage to power its load and the current bypassing the voltage regulator in the stage.
