Abstract
A fault-tolerant multiphase voltage regulator includes a plurality of power stages, each of which is configured to deliver a phase current to a processor, and a controller. The controller is configured to: control the plurality of power stages to regulate an output voltage provided to the processor; detect and disable a faulty power stage; generate a throttling signal to indicate if one or more of the power stages is faulty and disabled; and communicate the throttling signal to the processor over a physical line running between the processor and the controller. A corresponding method of operating a fault-tolerant power distribution system is also described.
