230V AC to 2...53V DC@6.6A Constant Current Source

Dear All!

I would like to ask for your suggestions.

I have to build a Power supply for a luminaire measuring device. It is a special one, because it has to supply the fittings with 6.6A constant current. Its power range must be between 15W and 350W. I have 230V/50Hz AC line voltage. I have seek for a suitable controller (maybe the UC28023?), which I can use for my application, but I am not sure so far.

Thank you for your help.

Best regards,

Gaspar
