Title: SYSTEM AND METHOD TO MANAGE POWER FOR PORT CONTROLLER BASED POWER SUPPLIES USING A COMMON POWER SOURCE
Abstract:
A system that delivers power between a common power source having a total deliverable system power and device loads. The system includes a power share interface that sums power consumed or requested by loads and determines availability of additional power. The system includes at least one peer power share interface with each peer interface associated with a port controller and communicable coupled to the power share interface over the system bus. The peer power share interface determines status of total power consumed or requested relative to total deliverable system power. The power share interface can in response to receiving the power level request cause the system to change power allocations to satisfy the power level requests.
