Abstract: A DC-DC converter includes an interface to receive data having voltage values. A first circuit carries out a voltage transition from a previously received voltage value to a received voltage value (VSEL). A second circuit activates or inactivates the first circuit in response to an activation signal or a stop signal provided by the interface. A third circuit configures the second circuit so that, when new data including a new voltage value is received during a voltage transition, the second circuit interprets the stop signal as an activation signal for the first circuit to carry out a new voltage transition. The setting circuit sets at least one parameter needed by the first circuit to carry out the new voltage transition in response to the new data and before the end of the new voltage transition.
