Abstract
A computing device is provided that includes a processor, a primary power supply, and a voltage regulation module. The voltage regulation module is configured to determine a load line for the processor and monitor a voltage and a current to the processor. While monitoring the voltage and current, the voltage regulation module is further configured to regulate the voltage to the processor to trend toward a voltage setpoint defined by the load line. While regulating the voltage, the voltage regulation module is further configured to clamp the load line at a clamping voltage to limit the regulated voltage output by the voltage regulation module from falling below a predetermined device minimum operation voltage when the monitored current exceeds a device maximum current value. The voltage regulation module is further configured to output electrical power at the regulated voltage to the processor.
