A distributed power management system may include a communication bus and a plurality of POL (point-of-load) regulators coupled to the communication bus and configured in a current sharing arrangement in which each POL regulator of the plurality of POL regulators has a respective output stage coupled to a common load and configured to generate a respective output current. Each POL regulator may have a respective phase in the current sharing configuration, and may transmit and receive information over the bus according to a bus communication protocol corresponding to the bus. The plurality of POL regulators may autonomously arbitrate a new master assignment, when a POL regulator operating as a master device drops out of regulation when a fault occurs, the respective phase of the master device is dropped, and/or the communication interface of the master device to the communication bus fails. The plurality of POL regulators may autonomously add and drop phases while automatically redistributing phase alignments of the POL regulators relative to one another. |
