Abstract
A control circuit for a voltage regulator includes a digital compensator having adaptive compensation to permit operation over different operating conditions. The digital compensator includes a gain parameter that is inversely proportional to the input voltage and is independent of the switching frequency. In embodiments, the voltage regulator has a crossover frequency established by at least one pole and at least one zero and the corner frequency of the converter output filter has a first fixed, predetermined relationship with respect to the switching frequency, a second fixed, predetermined relationship with respect to the crossover frequency, and a third fixed, predetermined relationship with respect to the at least one pole and at least one zero.
