Title: DC/DC converter

Abstract: A DC/DC converter including a switching transistor, an inductor, a smoothing capacitor, and a switching element which are connected so as to convert an input voltage U.sub.E to an output voltage U.sub.A greater or less than the input voltage U.sub.E. The current through the inductor can be measured by providing a comparator having a first input connected to the switching transistor, and a second input connected to a reference transistor and a reference current source so as to fix the switching threshold of the comparator at the second input.
