A switching converter according includes a control arrangement to furnish a control signal dependent on the output voltage, as well as a first and at least one second converter stage. Each converter includes an inductive storage element, a ramp signal generator to furnish a signal having a ramp slope, a pulse width modulator which receives the control signal and the ramplike signal and which furnishes a pulse width modulated signal, and a driver circuit which receives the pulse width modulated signal and the input voltage and which applies the input voltage to the inductive storage element depending on the pulse width modulated signal. The ramp slope of the ramplike signal of the at least one second converter stage is adjustable. The ramp signal generator of the second converter stage receives a calibration signal which depends on the inductance of the inductive storage element of the first converter stage.
