Systems and methods for DC-to-DC converter control

A method for controlling a number of phases that are active in a multiphase direct-current-to-direct-current (DC-to-DC) converter includes (a) filtering a current signal representing a magnitude of current processed by the multiphase DC-to-DC converter to generate a filtered signal, (b) comparing th...

Zusammenfassung:	A method for controlling a number of phases that are active in a multiphase direct-current-to-direct-current (DC-to-DC) converter includes (a) filtering a current signal representing a magnitude of current processed by the multiphase DC-to-DC converter to generate a filtered signal, (b) comparing the filtered signal to a first threshold value, (c) deactivating one or more phases of the multiphase DC-to-DC converter in response to the filtered signal falling below the first threshold value, (d) comparing the current signal to a second threshold value, the second threshold value being greater than the first threshold value, and (e) activating one or more phases of the multiphase DC-to-DC converter in response to the current signal rising above the second threshold value.
