Abstract:
A control module controls a switching converter including at least one inductor element and one switching element. The module includes: a driver circuit that generates a control signal which controls the on and off cycles of the switching element; a first modulation circuit which sends a command to the driver circuit in such a manner as to generate edges of a first type of the control signal, as a function of the input electrical quantity and of a reference electrical quantity; and a second modulation circuit which sends a command to the driver circuit in such a manner as to generate edges of a second type of the control signal, as a function of a first and a second internal electrical quantity, which are functions respectively of the charges on a first and a second capacitor, which are charged and discharged as a function of the control signal.
