Abstract
The disclosure relates to a method of generating an output voltage from a high input voltage and a command signal, the method comprising: generating an output voltage from a high voltage source; providing an inductor having a first terminal and a second terminal linked to a low voltage source by a capacitor, the second inductor terminal supplying the output voltage to a load; generating command signals as a function of a high voltage supplied by the high voltage source and the output voltage, to reduce a difference between the output voltage and a reference voltage lower than the high voltage; and connecting the first inductor terminal exclusively either to the high input voltage or the low voltage or to the inductor second terminal, as a function of the command signals.
