Abstract
A method, a power control system, and an information handling system (IHS) for operating voltage regulators (VRs) in an IHS. The method includes detecting, via a VR controller, a real time current level of a processor and receiving a first temperature value from a temperature sensor. The VR controller calculates a modified current level based on the real time current level, the first temperature value and a pre-defined temperature value and applies the modified current level to the processor.

A method for operating a voltage regulator (VR) in an information handling system (IHS), the method comprising:
- detecting, via a VR controller, a real time load current level of an associated processor;
- receiving a first temperature value from a temperature sensor;
- calculating a modified current level based on the real time current level, the first temperature value, and a pre-defined temperature value;
- and
- applying the modified current level to the processor.
A power control system comprising:
- a power subsystem configured to be coupled to and supply power to functional components of an information handling system (IHS) including a processor, the power subsystem including a voltage regulator (VR), the VR further including a VR controller, the VR controller having firmware executing thereon that configures the VR controller to:
- detect a real time load current level of an associated processor;
- receive a first temperature value from a temperature sensor;
- calculate a modified current level based on the real time current level, the first temperature value and a pre-defined temperature value;
- and
- apply the modified current level to the processor.
An information handling system (IHS) comprising:
- at least one processor;
- and
- a power subsystem communicatively coupled to the at least one processor and to functional components of the IHS, the power subsystem including at least one voltage regulator (VR) assigned to each of the at least one processor, the at least one VR further including a VR controller, the VR controller having firmware executing thereon that configures the VR controller to:
- detect a real time load current level of an associated processor;
- receive a first temperature value from a temperature sensor;
- calculate a modified current level based on the real time current level, the first temperature value and a pre-defined temperature value;
- and
- apply the modified current level to the processor.
