ABSTRACT:
A system and method for providing power control in a power management integrated circuit. A power management integrated circuit may comprise a communication interface module that receives power supply information from at least one electrical device external to the power management integrated circuit. The power supply information may, for example, comprise information related to a first electrical power. The power management integrated circuit may also comprise a power regulator module that determines a regulated power signal based, at least in part, on a portion of the power supply information. The regulated power signal may correspond to the first electrical power. For example, the regulated power signal may comprise the first electrical power or cause another circuit to output the first electrical power. The power management integrated circuit may then output the regulated power signal to at least one electrical device external to the power management integrated circuit.
