Abstract
A control device of a switching converter having an input terminal, an output terminal and a semi-bridge of a first and second transistor coupled between the input terminal and a reference voltage, includes a first circuit for detecting a signal representative of the signal on the converter output terminal and able to compare it with a reference signal and to emit a first signal in response to the comparison. The control device drives the first and second transistors based on the first signal and includes a protection circuit to detect the presence of overcurrents in the semi-bridge and acting upon the first and second transistors in response to the detection. The control device includes a second circuit for acting upon the first circuit in order to level the value of the first signal after the triggering of the protection circuit.
