Abstract: Systems, methods, and computer programs are provided for controlling power in a computing device. One embodiment is a system comprising a plurality of power rails coupled to one or more computing device components. Each power rail has a primary power supply for producing current at a corresponding requested voltage. The system further comprises a shared secondary power supply selectively coupled to the plurality of power rails for providing a current increase. A controller selects one of the plurality of power rails to receive the current increase. The controller generates a control signal to electrically couple the shared secondary power supply to the selected power rail to receive the current increase.
