1. Circuitry comprising:

  • switching circuitry having a switching circuitry output;

    a first parallel amplifier having a first feedback input and a first parallel amplifier output, such that a first inductive element is coupled between the switching circuitry output and the first feedback input; and

    the first parallel amplifier is configured to partially provide a first power supply output signal via the first parallel amplifier output and a second inductive element based on a voltage setpoint; and

    a second parallel amplifier having a second feedback input and a second parallel amplifier output, such that the second inductive element is coupled between the first feedback input and the second feedback input.
