Claim 0:
1. An isolated converter (100) for providing a current supply to an LED load, comprising:
a galvanic isolation stage (101);
a sensing circuit (103) on a primary side of the isolation stage (101), which is magnetically coupled to a secondary side of the isolation stage (101);
wherein the sensing circuit (103) is configured to receive a feedback signal that is proportional to a secondary side current; and
a control unit (105) configured to determine an output current of the converter (100) based on the feedback signal;
wherein at least one electrical characteristic of the sensing circuit (103) and/or the control unit (105) is adjustable to convert the feedback signal from a first ratio to a second ratio to the secondary side current, the converter (100) is designed to provide the output current in at least one dimming range, and the feedback signal is set to a fixed ratio to the secondary side current for all dimming ranges of the converter (100), wherein the fixed ratio depends on a maximum current level to be detected.
