The switching DC-DC converter comprises an inductor, a control circuit
with an oscillator and an output stage, the output stage being coupled to
the inductor, a diode coupled to the inductor, and a feedback loop for
generating a stabilized output voltage. An output voltage of the output
stage is coupled with an oscillator input of the control circuit, for
example via an impedance, for synchronizing an oscillation cycle of the
oscillator with a current pulse of the output stage.
