why not look at the cat4101 - less additional hardware needed to accomplish same thing
Yes I had a look at that driver too but exactly as Chagrin stated, I would waste a lot of power and would need a heat sink especially for strings that only have two LEDs and need 6 V.

Yes, that's it, Xenosaga. Word of caution though - while the datasheet states that 90K is the maximum recommended Rset value I believe that that translates to the datasheet's stated minimum 50ma of LED current (never fully off). The datasheet never fully answers that question and only shows current up to 35K (Fig. 7 pg. 3).
Thanks a lot! I think I will just get the components and see how and if it works and if not I will bug you guys with some questions about that inverted input on CTRL ; )
