Abstract

In various embodiments, a circuit arrangement may include a voltage-measuring device embodied to measure an output voltage, wherein the voltage-measuring device is embodied to provide at its output a signal which is correlated with the measured output voltage, wherein the voltage-measuring device is coupled to a control device for the purpose of transmitting said signal to the control device, and wherein the control device is embodied to vary an off-time as a function of the measured output voltage.
