A clocked electronic energy converter having an electronic switching element, at least two electrical energy storage devices, a terminal for connecting an electrical energy source, a terminal for connecting an electrical energy sink, a clock generator for controlling and operating the electronic switching element during switching operation and an adjusting unit which provides a first signal for adjusting the power-to-be-transmitted by the energy converter, is disclosed. The clock generator is designed to adjust the power-to-be-transmitted by the energy converter in a first output range by means of the switch-on time of the electronic switching element and, in a second output range in which the power-to-be-transmitted by the energy converter is less than in the first output range, to adjust the power-to-be-transmitted by the energy converter in the second output range by a combination of the switch-on time and the supplemental switch-off time, the supplemental switch-off time being constant.
