Claim 9:
10. A method of controlling a voltage converter, the voltage converter comprising a first transistor connected between a first node of the converter and a second node, a second transistor connected between the first node and a third node, a comparator comprising first and second inputs, and a selection circuit coupled to the first and second inputs, the selection circuit comprising three inputs, the method comprising:
receiving, at the second node, a power supply voltage;
receiving, at the third node, a reference potential;
controlling, by a first circuit, the first and second transistors;
receiving, from the selection circuit through the first input during a first phase, a first voltage ramp;
receiving, from the selection circuit through the second input during the first phase, a set point voltage;
receiving, from the selection circuit through the first input during a second phase, the set point voltage; and
receiving, from the selection circuit through the second input during the second phase, a second voltage ramp.
