1. A method for operating a voltage supply system, the method comprising:

  • generating a first output voltage with a charge pump of the voltage supply system based on an input voltage when in a first mode;

    delivering the input voltage as a second output voltage when in a second mode; and

    generating a third output voltage with a boost converter of the voltage supply system based on the input voltage when in a third mode, the boost converter including an input node, an inductor, and one or more switches, but no switch coupled between the inductor and the input node.
