Abstract
A regulated output voltage and an output current are generated by using a switching device for providing the output current and controlling the switching device with the first control circuit functioning in a pulse width modulation mode and in an alternative manner with a second control circuit functioning in a pulse frequency modulation mode. A second feedback circuit is included in the second control circuit and a time delay is introduced in the second feedback circuit in order to introduce a limitation of the pulse frequency.
