Abstract
An electronic arrangement includes a radiation source. A controlled voltage converter is configured to provide a lamp voltage for the radiation source for operating the radiation source in an ON state for a pulse duration, and to regulate the lamp voltage such that a reference voltage at a feedback terminal of the voltage converter is maintained substantially constant. A voltage source is connected to the feedback terminal and configured to provide, via the feedback terminal for acting on the regulation of the voltage converter, a time-dependent control voltage having a predefined time profile. The voltage converter is configured to select a time profile for the lamp voltage as a function of the predefined time profile of the time-dependent control voltage such that a power of the radiation source deviates from a constant power value by no more than 25% during at least 90% of the pulse duration.
