See TPS 61042 Texas Inst.
OK. thanks. This TI TPS 61042 is 30V inductive boost converter for 6 LED in series. Is there any other controller with more LED? How many more LED is optimum? Can I get more, such as 10 for 50V?

I'm guessing, but use 2 chips. 10 @50V is too much to ask I think, but I don't actually know. Maxim-ic.com do led drivers
