Abstract
In one form, a control circuit is adapted for use with a power converter having an inductor and a switch switching the inductor in response to a switching signal to regulate an output voltage of the power converter. The control circuit includes a slow feedback path, a fast feedback path, an integrator, a comparator, and a drive circuit. The slow feedback path provides a ripple signal in response to an average value of the output voltage. The fast feedback path provides a feedback signal in response to the output voltage. The integrator provides an error signal in response to a sum of the feedback signal and the ripple signal. The comparator provides a comparison output signal in response to a comparison of the error signal and a threshold voltage. The driver circuit provides the switching signal in response to the comparison output signal.
