Field: Computer technology (Electrical engineering)
Classification: CPC G  H  Y | IPC G  H

Claim 9:
10. An apparatus comprising:
an electrical load of a device integrated in the apparatus;
a voltage regulator connected to the electrical load;
a power supply pin configured to receive a current from a circuit board external to the apparatus;
a current sensing circuit of the device integrated in the apparatus, the current sensing circuit being connected to the power supply pin and the voltage regulator, the current sensing circuit being configured to measure the current from the power supply pin connecting the apparatus to the circuit board;
a controller of the device integrated in the apparatus, the controller being connected to the electrical load and the voltage regulator, the controller being configured to:
receive a current difference between the measured current and the target current;
in response to the current difference indicating the current measured from the power supply pin is greater than the target current, determine a first load control parameter to decrease an operating frequency of the electrical load;
in response to the current difference indicating the current measured from the power supply pin is less than the target current, determine a second load control parameter to increase the operating frequency of the electrical load;
generate a control signal based on one of the first and second load control parameters; and
apply the control signal to the electrical load to adjust the operating frequency, wherein the adjustment to the operating frequency adjusts current being consumed by the electrical load from an output voltage of the voltage regulator,

wherein the control signal is a first control signal, and in response to the controller receiving a default control signal, the controller is further configured to combine 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 device,
wherein the control signal applied to the electrical load to adjust the operating frequency is the second control signal.
