Classification: CPC H  Y | IPC H

Claim 8:
9. 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 settable to different ratios to the secondary side current in two or more portions of the dimming range.
