MaxFlex Prototype (production boards NOW available)
17 Oct 2006 update:
I guess I should clarify that the production boards are available (and have been for a week or so...)
------------------------------------------
23 Sept 2006 Update:
MaxFlex drivers should be available for shipping in the first week of Oct.
Drivers will be $30 each.
Firmware now includes both the UIP and UIF (use can reconfigure) that some of you are familiar with from the nFlex drivers.
Operating voltage is 2.7V - 20V.
MaxFlex is a current regulating boost driver (steps up).
Output voltage can drive up to 24V and output open circuit protected.
Max output current can be user configured (350/500/700/1000/1200/1400mA)
User configurable sleep mode, force level.
User configurable low voltage protection and warning.
More info can be found in the MaxFlex sections of www.taskled.com.
Note, the original description below was based on a Fatman core (12V in, 16v out max). MaxFlex is based on a different switcher IC, hence the new 20V in, 24V out max specs.

--------------------------------------------
FatFlex - what you get when you mate a Fatman with an nFlex:
Looks like a Fatman from the top (far left shows the momentary action switch, behind you can see a LuxV lit at the dim level):
Doesn't look like a Fatman from below (the blue wire mess is just to access the programming pins of the uC on the prototype) /ubbthreads/images/graemlins/grin.gif
At this point the firmware is 100% nFlex, but I'm thinking of rolling some of the UI1 LionHeart features into the firmware to make it more 'flashlight' friendly vs fixed lighting friendly.
Anyhow, lots more testing to do, but I figured some of you would be interested to see what the next driver I'll most likely be taking to production looks like. Probably a month or so off in the future at this stage.
