Abstract
The disclosure relates to a method of generating an output voltage, comprising: generating a regulated 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; connecting the first inductor terminal exclusively either to the high voltage source or to the low voltage source or to the second inductor terminal, as a function of command signals to reduce a difference between the output voltage and a reference voltage lower than a high voltage supplied by the high voltage source; and generating a square binary control signal having a duty cycle substantially adjusted to the ratio of the output voltage to the high voltage; the first inductor terminal being connected to the high voltage source or to the low voltage source as a function of a binary state of the control signal.
