Patent ID: 7936089

Claim:
A system, comprising: a module comprising: a component, a logic device to provide an instruction to a board to power up a power supply, on the board, that is powered down, the provided instruction including start-up timing information and power-down timing information, the power supply being powered up based on the start-up timing information, where the power supply is powered down, after being powered up, based on the power-down timing information, and control logic to: receive, from the board and in response to the provided instruction, a constant current, generate, in response to receiving the constant current from the board and based on a desired voltage that the component is to operate with when performing an operation, a desired output voltage signal, where the desired output voltage signal corresponds to the desired voltage that the component is to operate with when performing the operation, and send the desired output voltage signal to the board, where the logic device and the control logic are physically separate; and the board comprising: the power supply to produce, based on the desired voltage signal, the desired voltage, and an interface to: send, in response to receiving the provided instruction, the constant current to the control logic, receive the desired output voltage signal from the control logic, and send the desired voltage to the component to allow the component to perform the operation, in response to receiving the desired output voltage signal.
