Abstract
A control device for a switching converter, the converter having at least one transistor supplied by an input voltage and adapted to supply a load by means of an output voltage. The converter also including a circuit adapted to turn on and off the at least one transistor. The control device includes an operation circuit adapted to change the state of the at least one transistor from turned on to turned off or vice versa, respectively when the output voltage goes down or goes up by a first voltage of a given value by defining a first state; the operation circuit including a further circuit adapted to generate a ramp signal and to change the first state of the at least one transistor from turned on to turned off or vice versa when the ramp voltage is equal to the output voltage of the converter.
