Methods and systems for controlling current consumption by an electrical load of a first circuit board are described. In an example, a device of a first circuit board can measure a current being drawn by the electrical load of the first circuit board from a second circuit board. The device can generate a control signal based on a current difference between the measured current and a target current. The control signal can represent a load control parameter. The device can apply the control signal to the electrical load of the first circuit board to adjust a current consumption by the electrical load.
