Abstract
A power converter circuit includes a power stage circuit configured to convert an input voltage to provide an output voltage. A feedback control circuit is configured to generate an error signal based on the output voltage and a reference voltage. An offset circuit is configured to apply an offset signal to the error signal based on change in a modulating frequency of a clock signal to provide an adjusted error signal. A driver circuit is configured to drive the power stage circuit based on the adjusted error signal and the clock signal.
