Abstract
A controller for use in a power converter comprising a feedback reference circuit coupled to receive a feedback signal representative of an output voltage of the power converter. A feedback reference circuit generates a drive signal in response to the feedback signal and the drive signal is used to control switching of a power switch of the power converter to regulate the output voltage. The controller further comprises an output power control circuit coupled to receive a current sense signal representative of an output current of the power converter and a power signal representative of a desired value of an output power of the power converter. The output power control circuit generates an adjust signal to adjust the feedback signal such that the controller modifies the output voltage to regulate to the desired value of the output power.
