A control system for a switching DC-DC converter is proposed. The converter includes an input terminal for receiving an input voltage from a source, a control terminal adapted to receive a switching control signal, and an output terminal for providing to a load an output voltage generated from the input voltage according to the control signal. The control system includes detecting means for detecting a reaching condition of a predetermined value by a current provided to the load by the converter and control means for controlling the control signal according to the output voltage. The control system further includes disabling means for disabling the supply of the control signal to the control terminal according to the detection of the reaching condition. The disabling means includes selection means for controlling the disabling according to a time relationship between the detection of the reaching condition and the control signal.
