Abstract
A regulated voltage-boosting device provides a charge-pump circuit, which has an input terminal receiving a first voltage and an output terminal supplying a second voltage higher than the first voltage. The regulated voltage-boosting device provides a plurality of voltage-boosting stages that can be selectively activated and deactivated. The regulated voltage-boosting device provides an automatic-selection circuit for activating a number of voltage-boosting stages which is correlated to the first voltage and to the second voltage.
