Claim One:
1. A method of selecting an output stage configuration per selected operating performance point (OPP) for a switched mode power supply having a plurality of selectable, parallel output stages, each operative to supply current to a load, the power supply operative in a system that switches between discrete OPPs, the method comprising: upon receiving notice that the system has switched to a first OPP, retrieving historic output stage configuration data associated with the first OPP; configuring the output stages according to the historic output stage configuration data; during operation at the first OPP, periodically monitoring a current drawn by the load; adjusting the output stage configuration based on the current monitoring; and upon receiving notice that the system has switched to a second OPP, updating the historic output stage configuration data associated with the first OPP to reflect the output stage adjustment, and storing the updated historic output stage configuration data in association with the first OPP; wherein the historic output stage configuration data associated with the first OPP comprises at least; a mapping of the first OPP to a running average, over a predetermined number of iterations of the first OPP, of a determined optimal number of output stages to be enabled; and a mapping of the first OPP to a running average, over a predetermined number of iterations of the first OPP, of deviations in the number of output stages enabled.
