Abstract
A controller, and related method, configured to generate a duty cycle control signal for controlling an output voltage of a switched mode power supply as a function of a reference signal. In one embodiment, the controller is configured to sample a signal indicative of the output voltage to generate a first sampled signal, filter out a ripple component of the first sampled signal to generate a filtered signal, and generate a feedback control signal based on the filtered signal. The controller is also configured to sample a signal indicative of an input voltage of the switched mode power supply to generate a second sampled signal, generate a feed-forward control signal based on the second sampled signal and a feed-forward reference voltage, and generate the duty cycle control signal based on the feedback control signal and the feed-forward control signal.
