Beschreibung
Zusammenfassung:	A method includes sensing, using a current sensing circuit of a voltage regulator, an apparent amount of current output from the voltage regulator and identifying a present value of at least one operating parameter for the voltage regulator. The method further includes determining at least one current sense correction factor as a function of the identified present value of the at least one operating parameter, and calculating a corrected amount of current output from the voltage regulator as a function of the apparent amount of the current output and the at least one current sense correction factor. Still further, the method includes reporting the corrected amount of current to an integrated circuit that receives current output from the voltage regulator. The method may be performed in an apparatus, such as a server, that includes the voltage regulator, a baseboard management controller, and the integrated circuit.
