Can i check if it is possible to drive the LM3414 to a constant current of 200mA?

It is workable on the Webench

Ivan:

The LM3414 data sheet recommends LED current 350mA to 1A. If you use it for 200mA operation, the LED current is probably not going to be as accurate. There are other TI parts like LM3402 works better at 200mA.
