Abstract: A converter circuit includes an input node for receiving an input signal and an output node for providing a converted output signal to a load, a switching power stage to receive the input signal and an on-off drive signal switching between an on-state and an off-state, and a reactive output network coupled to the switching power stage and configured to provide the converted output signal to the load. The converter circuit comprises a first feedback signal path configured to generate a PWM-modulated control signal for the switching power stage as a function of the converted output signal, and a second feedback signal path including an output variation sensing circuit to generate at least one output variation signal indicative of variations of the converted output signal over time.
