Abstract: A switching control method for level shifter includes a phase of de-selection of a high voltage value at an output terminal of the shifter using a selection signal. The de-selection phase may include starting the de-selection by bringing the selection signal to a low value; de-activating by way of the selection signal, the generation of a high-voltage signal being supplied to the shifter, and a reference voltage signal; computing the difference between an internal voltage signal of the shifter and the reference voltage signal; generating a control signal when the difference is found to be less than a threshold voltage value; and applying the selection signal to an input terminal of the shifter in the presence of the control signal.
