Patent ID: 8242759

Claim:
A method comprising: maintaining threshold information to include a first threshold value and a second threshold value, the first threshold value representing a peak current threshold value, the second threshold value representing a filtered current threshold value; receiving a first value indicative of a peak magnitude of current delivered to a dynamic load during a window of time, the first value being a peak current value derived from multiple samples of the current taken during the window of time; initiating comparison of the first value to the first threshold value of the threshold information; and receiving a second value indicative of a magnitude of current delivered to the dynamic load; initiating comparison of the second value to the second threshold value of the threshold information; and based at least in part on the comparison, adjusting how many phases of a power supply are activated to produce the current delivered to the dynamic load; responsive to detecting that the first value is less than the first threshold value and the second value is less than the second threshold value, reducing a number of phases of the power supply that are activated to produce the current delivered to the dynamic load.
