^ I haven't been active at LPF in quite some time. I'll post a link to this thread over there and also to your complete build product page and just tell them I don't know how well it would work with most laser diodes, but it sounds promising. It does sound interesting. I have a couple laser diodes I've been wanting to use. I will probably use this driver for them.
Not sure I understand the 4 layer thing, but I sounds like a very good thing. Thanks for developing it. Definitely the way I will go when I get or make one of these neat drivers.

It would work, except that you can't even hardly see that pin on that MCU unless it is specifically broken out.
Well, hopefully MRsDNF will have enough of the board's contact pad exposed to solder a thin wire to. Momentary switches can use very thin wires.
Parts kit. The parts needed are the same, except I can only recommend using Coilcraft XAL6060 inductors at these drive levels and there are 2x diodes instead of one. The second diode basically just heatsinks the first, but it works. The second input capacitor is optional. After reflow, fill the exposed copper on the FET's drain pad with solder for increased thermal conductivity and decreased electrical resistance.
Here are some pictures for those you looking to build your own. The regular (non-HP) version is pretty much the same, so you can use these to guide you with it as well.
This driver is awesome in the 1405. I've been playing with one of RMM's four layer buck drivers set at five amps in a 1405 for a couple months now and the driver has held up flawlessly. The four layer MTN MAX combined with a dedomed XM-L2 in the 1405 lights up the treeline out back of my house at 500 yards easily. I'm guessing it will do twice that range but I haven't confirmed that. I've also put one of RMM's two layer MTN MAX drivers at 3.5 amps into a mini mag running triple XP-Ls. That was a cool little light.
That’s cool! I am waiting for my parts from Richard to arrive but I am going to push the dedomed S4 2B at “only” 4.5A for reliability concern. How much candela would you expect at 4.5A?
