Abstract
A system and method for implementing a common control bus in a multi-regulator power supply integrated circuit. The integrated circuit may, for example, comprise first and second power regulator modules that control at least one characteristic of respective power signals. The integrated circuit may also, for example, comprise a communication interface module that receives power control information related to operation of the first and second power regulator modules over a shared data bus. An exemplary method may, for example, comprise receiving power control information over a data bus. The method may also, for example, comprise determining which of a plurality of power regulators corresponds to the received power control information. The method may further, for example, comprise determining a regulator control signal, based at least in part on the received power control information, and provide the regulator control signal to the determined regulator(s) to control operation of the determined regulator(s).
