The circuit comprises stages connected in series to produce by transfer of loads between stages an output voltage derived from a feed voltage. The circuit comprises devices (REG,CC) for reducing or increasing the number of stages connected, in terms of the value of the voltage produced, so that the number of stages connected is adapted to the number of stages necessary in order to attain a given output voltage value, taking into account the value of the feed voltage. Commutation devices connect selectively at least one outlet of a stage (Cn-1) to and inlet of another stage or to a circuit outlet (S). A regulating circuit comprises comparison devices to compare the value of the output voltage produced (Vout) with an incrementation threshold with one of diminution. Devices are also provided for comparing the value of the voltage produced with a regulation threshold included between the thresholds of incrementation and of diminution in order to produce a first command signal (HIGH) representing the result of this comparison. |
