Abstract
A multiphase regulator includes a plurality of output phases, each operable to deliver a phase current through a separate inductor to a load connected to the output phases via the inductors and an output capacitor. The multiphase regulator further includes a controller operable to regulate a voltage delivered to the load by adjusting the phase currents delivered to the load by the output phases, and monitor the phase currents delivered to the load by the output phases. The controller is further operable to determine if the monitored phase currents indicate any of the individual output phases, any of the individual inductors or the output capacitor are faulty, even if the total current delivered to the load is within specified limits.
