Abstract
One embodiment of the invention includes regulation voltage system for a power supply system. The system includes a current sense system configured to generate a sense signal that represents an output current of the power supply system that is supplied to a load. The system also includes a positive voltage droop controller configured to provide a regulation voltage to the power supply system, the positive voltage droop controller setting the regulation voltage to one of a predetermined fixed reference voltage or a variable reference voltage based on the sense signal. The variable reference voltage can be less than the predetermined fixed reference voltage.
