1. An integrated circuit comprising:
- a switching voltage regulator (SVR) comprising one or more bridge drivers to provide regulated power supply to a plurality of power domains that comprise a first power domain and a second power domain, wherein the SVR is operable to provide a plurality of switching frequencies including a first switching frequency and a second switching frequency; and
a power control unit (PCU) operable to adjust the switching frequencies of the SVR according to states of the plurality of power domains, wherein at least one of a drive strength and an active phase count of the one or more bridge drivers is adjusted by a logic unit of the SVR when at least one of the switching frequencies of the SVR is adjusted, wherein the first power domain is optimized using the first switching frequency and the second power domain is optimized using the second switching frequency.
