POWER SUPPLY CONTROLLER WITH DIFFERENT STEADY STATE AND TRANSIENT RESPONSE CHARACTERISTICS

摘要

An embodiment of a power-supply controller includes a control circuit and a detection circuit. The control circuit has a signal characteristic, and is operable in response to a regulated output signal and a reference signal to cause at least one power-supply phase to generate the regulated output signal. The detection circuit is operable to detect a change in the regulated output signal, and to alter the signal characteristic of the control circuit in response to the detected change.
