A method for controlling a voltage step-down converter (20) including an inductive component (21), one terminal of which is connected to an electrical source (50) via a regulating switch (24), while its other terminal is connected to a capacitive component (22), the output of the voltage step-down converter being regulated by alternating connection intervals, during which the regulating switch is in an on state, with disconnection intervals, during which the regulating switch is in an off state, the regulating switch being switched from the on state to the off state when the value of the output voltage reaches a disconnection threshold. The disconnection threshold has a variable value which decreases progressively, during each connection interval, from a maximum value of the disconnection threshold.
