ABSTRACT:
Multiple components of a computer system may be capable of entering wake and sleep states. The power consumption of a processor during wake state may draw significant amount of current. In order to keep power consumption of a voltage regulator low, a two-phase voltage regulator may be used during wake state. During sleep state, since power consumption is lower, the two-phase voltage regulator may be operated in a single-phase mode to further reduce voltage regulator power consumption.
