Title: SYNCHRONOUS DOWN-CONVERTER FOR OPERATING ONE OR MORE ILLUMINANTS, ASSOCIATED METHOD AND OPERATING UNIT
Abstract:
The invention relates to a synchronous down-converter for operating one or more illuminants, wherein the synchronous down-converter is configured to be operated in a first mode of operation or in a second mode of operation, wherein in the first mode of operation of the synchronous down-converter current flowing through the synchronous down-converter rises and falls alternately and wherein in the second mode of operation the current profile of the current flowing through the synchronous down-converter decays over a predetermined period. Further, the invention relates to a corresponding method for operating one or more illuminants and to an operating unit that has the synchronous down-converter and is configured for operating the one or more illuminants.
