Abstract
A control device for a converter of the switched-mode type provided with an inductor element and a switch element generates a driving signal for controlling switching of the switch element and determining alternately a phase of storage of energy in the inductor element as a function of an input quantity and a phase of transfer of the energy stored in the inductor element to an output element on which an output quantity is present; the control device generates the driving signal by means of a control based on the value of the output quantity in order to regulate the same output quantity. In particular, an estimation block determines an estimated value of the output quantity, and a driving block generates the driving signal as a function of said estimated value.
