Thanks Cheesehead!

Let me know if you want any PCB build files for the LM3409. I've been playing around with a few different designs lately and found that they're a lot more flexible with their input voltages/ output voltages, than I'd previously thought. I'd built most of mine to drive 50 watt BridgeLux multi-emitter arrays that have a Vf of 24.4v and need 2,000 ma, but I've found that the same drivers will also drive much higher voltages and lower currents too.
