In accordance with one embodiment, a switching converter includes a switching circuit configured to receive a switching signal and to alternatingly connect an output node of the switching circuit with a supply node and a reference node in accordance with the switching signal. An input voltage is operably applied between the supply node and the reference node. The switching converter further includes an inductor coupled between the output node of the switching circuit and an output node of the switching converter as well as an oscillator configured to generate a clock signal with an oscillator frequency depending on the input voltage. A switching controller is configured to receive the clock signal and to generate the switching signal using pulse-width modulation (PWM), wherein the frequency of the switching signal is set in accordance with the oscillator frequency and a duty cycle of the switching signal is deter-mined using current-mode control.
