Hey,
So I'm building another full custom light in an interesting aluminum housing and I'm having a little trouble finding an appropriate boost regulator that will handle the power.
I'm looking to have 4 to 6 high current nimh AAA cells driving 3 SSC P4 LEDs at around 1000 mA max. Battery life at max will be short. Lithium-ions aren't being considered. I'm just trying to find a driver that works at around this level with 4 AAA cells:
4.8v input @ 2570 mA ->11v output at 1000 mA
If the cells can't handle it, then I guess 6 AAA cells:
7.2v input @ 1720 mA -> 11v output at 1000 mA (all assuming 90% efficiency).
The Sandwich Shoppe Shark board seems to handle it, but it's very hard to find in stock. Also, I'd prefer a single electronic control for brightness instead of a pot mounted on the outside of light (it's a small light). The TaskLED Fatman can't easily handle 2570 mA, and the MaxFlex is still under development.
Are there any other boards that can handle this? Many thanks!
