Abstract
According to one configuration, a multi-phase power supply adjusts a number of active phases based at least in part on a peak current supplied to a dynamic load. For example, a controller associated with the multi-phase power supply can monitor or receive a value indicative of a peak magnitude of current delivered by the multi-phase power supply to a dynamic load. The controller initiates comparison of the value to threshold information. Based at least in part on the comparison, the controller adjusts how many phases of the multi-phase power supply are activated to deliver the current delivered to the dynamic load. Thus, one embodiment herein is directed to controlling a multi-phase power supply based at least in part on a measured parameter such as peak current magnitude.
