A converter, for feeding a load via an inductor with a current having a controlled intensity between a maximum and a minimum level, includes a switch to permit or prevent, respectively, current towards said inductor, a first current sensor sensitive to the current flowing through switch when the switch is on, a second current sensor sensitive to the current flowing through said inductor when the switch is off, drive circuitry to turn the switch off and on upon receiving a first and a second logic signal, respectively, and comparison circuitry coupled to the first and the second current sensors to generate first and the second logic signals when, respectively: the current intensity detected by the first current sensor is offset a given amount with respect to the maximum level, and the current intensity detected by the second current sensor is offset a given amount with respect to the minimum level. |
