Abstract
In an embodiment, a voltage converter is configured to operate by a succession of operating cycles, each cycle comprising an energy accumulation phase and an energy restitution phase, wherein the converter is further configured to determine a duration of one of the phases by comparing a voltage ramp and a first reference voltage, and wherein a slope of the voltage ramp depends on a sign of a current in an inductor at an end of a previous operating cycle.
