Abstract
For use with a switched-mode power converter having a modulator that develops a drive signal for a power switch, a compensation circuit, a method of compensating for a change in an output characteristic of the converter and a converter employing the circuit or the method. In one embodiment the compensation circuit includes (1) a sensor that senses the output characteristic and (2) a filter, coupled to the sensor, that develops an intermediate signal representing a change in the output characteristic. The modulator adjusts a switching period of the drive signal as a function of the intermediate signal thereby to decrease a reaction delay of the converter.
