  • ADAPTIVE SPARE STAGES IN CONFIGURABLE VRM CARD
    Publication number: 20240103549
    Abstract: A discrete VRM card includes a first VRM controller and a second VRM controller. The discrete VRM card also includes a first primary power stage, a second primary power stage, and an adaptable spare stage. The discrete VRM card includes a first switch and a second switch. Closing the first switch connects the adaptable spare converter with an output of the first primary power stage. Closing the second switch connects the adaptable spare converter an output of the second primary power stage.

  • Dynamic adjustment of power supply ripple ratio and frequency in voltage regulators
    Patent number: 11747875
    Abstract: One or more sampling parameters of an application associated with a downstream voltage regulator may be determined. A power supply rejection ratio (“PSRR”) and a switching frequency of an upstream voltage regulator may be dynamically adjusted based on the sampling parameters of the application associated with the downstream voltage regulator. The sampling parameters may include a noise level and a workload of the selected application.

  • Configurable VRM card
    Patent number: 11644878
    Abstract: A discrete VRM card comprises a set of VRM controllers. The set of VRM controllers comprises a VRM controller with two feedback loops. The VRM card comprises a power stage and a power-stage critical-signal multiplexer. The output of the power-stage critical-signal multiplexer determines a feedback loop with which the power stage communicates. The VRM card also comprises a configuration selector. The configuration selector determines a feedback-loop assignment for the power-stage critical-signal multiplexer and provides VRM instructions to the VRM controller.
