Abstract:
A control device of a switching converter controls the closing and opening of a switch of the converter that regulates the operation of an inductor. The control device includes a ramp voltage generator, a switch control circuit configured to close the switch based on a comparison of the ramp voltage with a first signal and a generator control circuit configured to control the ramp voltage generator based on a value of a second signal representative of a current flowing through the inductor of the converter, in comparison with the value of a third signal.
