Abstract
An exemplary extended switched-mode controller is provided for controlling the switching of a switched-mode power converter. This exemplary extended switched-mode controller further comprises a standard switched-mode controller and an auxiliary controller configured to receive standard switch control signals from the switched-mode controller and to (1) pass the standard switch control signals to the switched-mode power converter during non-transient operation, and (2) provide auxiliary switch control signals to the switched-mode power converter during transient operation instead of the standard switch control signals. The auxiliary controller is further configured to determine when to provide the auxiliary switch control signals and to determine what control signals to provide at least partially based on an auxiliary feedback input signal comprising at least one of: sensed converter voltages, converter currents, and an error signal. Where the error signal is at least partially based on the difference between a feedback signal and a reference signal.
