DIGITAL VOLTAGE REGULATOR CONTROLLER WITH MULTIPLE CONFIGURATIONS

摘要

A digital voltage regulator controller includes control logic, an interface and configuration logic. The control logic is operable to control power stages of a voltage regulator so that groups of one or more of the power stages individually regulate one or more output voltages of the voltage regulator. An external electrical parameter that indicates a location of the controller on a board or a version of the board is measured via the interface. The configuration logic is operable to determine a set of configuration parameters for the voltage regulator based on the location of the controller on the board or the version of the board as indicated by the external electrical parameter, and configure the control logic in accordance with the set of configuration parameters so that each output voltage is regulated based on the location of the controller on the board or the version of the board.
