Abstract
Described herein is an integrated circuit which comprises: a switching voltage regulator (SVR), having one or more bridge drivers, to provide regulated power supply to a plurality of power domains; and a power control unit (PCU) operable to adjust switching frequencies of the SVR according to states of the plurality of power domains, wherein drive strength or active phase count of the one or more bridge drivers is also adjusted by a logic unit of the SVR when the switching frequencies of the SVR are adjusted.
