Claim 16:
17. A method for controlling current consumption by an electrical load, the method comprising:
measuring, by a device on a first circuit board, a current being drawn by an electrical load of the first circuit board from a second circuit board, wherein the current is measured from a power supply pin of the first circuit board that connects the first circuit board to the second circuit board;
in response to a current difference between the measured current and a target current indicating the current being drawn is greater than the target current, determining, by the device on the first circuit board, a first load control parameter to decrease an operating frequency of the electrical load in the first circuit board;
in response to the current difference indicating the current being drawn is less than the target current, determining, by the device on the first circuit board, a second load control parameter to increase the operating frequency of the electrical load in the first circuit board;
generating, by the device on the first circuit board, a control signal based on one of the first and second load control parameters; and
applying, by the device on the first circuit board, the control signal to the electrical load in the first circuit board to adjust the operating frequency, wherein the adjustment to the operating frequency adjusts a current consumption by the electrical load,
wherein the control signal is a first control signal, and in response to the controller receiving a default control signal, the method further includes combining the first control signal with the default control signal to generate a second control signal, the default control signal representing a default load control parameter received from another device external to the first circuit board,
wherein the applying, by the device on the first circuit board, the control signal to the electrical load in the first circuit board to adjust the operating frequency includes applying the second control signal to the electrical load in the first circuit board to adjust the operating frequency.
