ABSTRACT:
The method controls a charge pump generator having at least an output tank capacitor on which a regulated output voltage of the generator is produced, and a pump capacitor that is connected to a supply node and to ground during charge phases and is coupled in an anti-parallel configuration to the output tank capacitor during charge transfer phases, alternated to the charge phases. The method limits the current absorbed from the supply because the transfer capacitor is charged during at least an initial charge phase with a constant charge current of a pre-established value.
