A DC-DC switching converter includes power switches selectively coupling an output terminal with a first voltage or with a second voltage. A driver stage is coupled with the power switches for driving the power switches. A driver control stage is coupled with the driver stage for controlling the operation of the driver stage. An output current sensing circuit is coupled with the output terminal and with the driver control stage, and is configured to sense a sign of an output current delivered by the DC-DC switching converter at the output terminal and to generate control signals for the driver control stage. The driver control stage controls the operation of the driver stage according to states of the control signals received from the output current sensing circuit, for selectively delaying the activation of the power switches depending on the sensed sign of the output current.
