1. A VRM system comprising:
VRM control logic circuitry;
a first output group that comprises a first primary converter;
a second output group that comprises a second primary converter;
a first VRM output and a second VRM output;
a first adaptable spare converter, wherein the first adaptable spare converter comprises a single VRM controller and a single phase and wherein the single VRM controller monitors a voltage of a feedback loop of the single phase;
a first switch, wherein closing the first switch connects the first adaptable spare converter with the first VRM output;
a second switch, wherein closing the second switch connects the first adaptable spare converter with the second VRM output; and
a third switch, wherein closing the third switch enables the VRM control logic circuitry to send instructions to the first adaptable spare converter;
wherein the single VRM controller within the first adaptable spare converter does not control the first switch, second switch, or third switch.
