POWER MANAGEMENT CIRCUIT WITH PER ACTIVITY WEIGHTING AND MULTIPLE THROTTLE DOWN THRESHOLDS

A method is described. The method includes receiving an indication of an activity of load circuitry of a power supply. The method includes, in response to the indication, generating a first signal that describes the activity and a second signal that describes whether the event is initiating or completing. The method includes determining a weight amount from the first signal and adjusting a credit count by the weight amount up or down based on the second signal. The method includes comparing the credit count against a first threshold. The method includes calculating an average credit count that accounts for the credit count and previous credit counts and comparing the average credit count against a second threshold. The method includes adjusting an activity level of the load circuitry if either threshold is crossed.
