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?
I think I’ve got it working, but next time I’ll just order the completed driver. I can deal with all the caps and tiny resistors, but I hate these components that have the pins under them.
I have the c682 coilcraft inductor. At the bottom it has 2 contact plates on each side and a black pad in the centre. I presume the black pad is the termal pad? Richard mentions one has to reflow the thermal pad? On the pcb underneath the black/thermal pad theres silkscreen, no place for reflowing? What is meant by reflowing the thermal pad of the inductor to the pcb?
