1. A method, comprising:

  • determining information about a first power delivery stage for a plurality of operating condition values as the first power delivery stage supplies power to a first load, the first power delivery stage being associated with a voltage regulator integrated with a processor die, the determined information including a plurality of values usable as initial conditions for an adaptive loop associated with an adaptive tracking controller;

    storing the determined information including the plurality of values in a dynamic look-up table of the adaptive tracking controller engine;

    updating the plurality of values that are stored in the dynamic look up table as the first power delivery stage supplies power to the first load;

    sensing an input to the first power delivery stage and an output from the first power delivery stage using a first controller that exchanges information with the adaptive tracking controller engine;

    determining information about a second power delivery stage associated with a second controller as the second power delivery stage supplies power to a second load; and

    using the adaptive tracking controller alternately between the first power delivery stage and the second power delivery stage.
