Abstract: A method and apparatus for performing dynamic current scaling of an input current of a voltage regulator are provided. The method and apparatus allow tuning current consumption in various applications, calculating a duration of an activity phase in which various algorithms are executed and activating dynamic current scaling of a regulator if the activity duration is shorter than a programmable threshold. A controller receives a threshold for an activity duration and a window size in which to evaluate the activity duration.
