PEAK CURRENT SUPPORT FOR A POWER RAIL SYSTEM VIA A SHARED SECONDARY POWER SUPPLY
First Claim
1. A method for controlling power in a computing device, the method comprising:
- selecting one of a plurality of power rails to receive a current increase, each of the plurality of power rails having a corresponding primary power supply for producing current at a corresponding requested voltage;
generating a control signal to electrically couple a shared secondary power supply to the selected power rail to receive the current increase; and
the shared secondary power supply providing the current increase to the selected power rail.

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.
