A circuit for emulating a current via a power inductor of a DC-to-DC converter includes means for generating a first signal and operable for detecting or emulating the constant component of the current via the power inductor and having first elements for generating the first signal, means for generating a second signal or components of the second signal and operable for emulating the alternating component of the current via the power inductor, and means for splicing the first signal and the second signal, or the first signal and the components of the second signal, into a signal which at least partially emulates the current via the power inductor, with the first elements of the first means including a current sensing resistor connected on the one hand to the power inductor and a first capacitor, and on the other hand to the first input and output.
