摘要： A switching converter includes a control arrangement and multiple converter stages. The control arrangement generates a control signal dependent on the output voltage. Each converter stage includes an inductive storage element, a current measurement arrangement that detects a current across the inductive storage element and furnishes a current measuring signal proportional to this current, a pulse width modulator that receives the control signal and the current measuring signal and generates a PWM signal, and a driver circuit that applies the input voltage to the inductive storage element in dependence on the PWM signal. The current measurement arrangement of a second converter stage adjusts a proportionality factor between the current across the inductive storage element and the current measurement signal thereof, responsive to an adjustment signal that is dependent on a proportionality factor between a current across the inductive storage element and the current measuring signal of a first converter stage.
