Abstract
A controller for a multi-phase switching regulator includes an error amplifier configured to generate an error signal indicative of the difference between a feedback voltage and a reference voltage; a loop calculator configured to generate control signals in response to the error signal to drive the power stages; and a dynamic phase management control circuit configured to generate a power efficiency value in response to the input current, the input voltage, the output current, and the output voltage. The dynamic phase management control circuit generates a phase selection signal indicating a first number of power stages to be activated in response to the first current signal and the power efficiency value. The phase selection signal is provided to the loop calculator to activate the first number of power stages.
