Energy transfer circuitry coupled to the energy storage circuit transfers energy stored in the energy storage circuit to an output node. A driver circuit coupled to the energy transfer circuitry switches the energy transfer circuitry between a state where energy from the first signal is stored in the energy storage circuit and a state where energy stored in the energy storage circuit section is delivered to the output node. A voltage at the energy storage circuit varies between an upper value and a lower value around a voltage setting point. A second generator, which is a scaled-down replica of the first generator, produces a second signal that is indicative of an open-circuit voltage of the first generator. The driver circuit uses the second signal to set the voltage setting point.
