Abstract: A charge pump circuit, connected between a first voltage reference and an output terminal, comprises at least two stages comprising an elementary charge pump circuit connected between said first voltage reference and said output terminal, and adjustment circuitry connected between said output terminal and respective control terminals of said at least two stages. This circuitry is arranged to select for actuation an appropriate combination of these elementary stages according to the current absorbed from a load connected to the output terminal.
