Abstract

A power control system comprises a plurality of power control groups (120), with each group comprising a plurality of individual point-of-load regulators (124) each adapted to provide respective regulated voltage outputs. The point-of-load regulators (124) may be selected for inclusion in a power control group based on characteristics of loads supplied by the point-of-load regulators. An intermediate bus controller (102) is coupled to each of said power control groups through a serial data bus interface common to each group and an OK status line for each respective group, the plurality of point-of-load regulators of each group each further comprises a respective fault manager (168) adapted to detect fault conditions and selectively communicate notifications of the fault conditions to the other ones of the plurality of point-of-load regulators of the group and to the intermediate bus controller.
