no particular light in mind but I prefer them to be 17mm dia (first one is larger, I know, but I did not find 17mm alternative) and AttinyA13 based drivers so I could flash modes.
For both lights I would choose the A17DD-SO8, for the last one with a zener diode.
One sided, no 7135 chips, the FET is widely available and high current depending on battery.
OK, thanks for your input fingers, in my country actually it is not that easy to find SMD stuff if you want to buy 1 piece so I have to check first what components I can get, fingers crossed :bigsmile: …
Here are some 10mm & 12mm Single-Sided FET drivers. The 10mm has been built and tested thoroughly, both inside and outside of a flashlight. These give you all of the performance of "big" FET driver in a tiny package, while staying single-sided.
-A very useful size for a couple of AAA-flashlights (Ultrafire M5, Ultrafire LZZ-06 and clones) is 11mm as well, can you make that one too?
-I do not have the knowledge to sort that out, can anyone find out an ebay-link to a LFPAK33 FET for this driver? I can not judge if one is suitable, and all I seem to find are ones that are over 3 dollars each.
djozz, are you sure about the Ultrafire LZZ-06 driver being 11mm, my Jexree Mini that i thought was as far as the body & head goes (they have only different reflectors) would be the exact same light is a 11,6mm driver.
I looked up this FET on Ebay and found no sellers that sell them for less than 3 dollars a piece plus $4.50 shipping :-(
To search Ebay succesfully I -unfortunately- was forced to look into all those different FET-packages :tired: . In the end I found this graphic somewhere in a NXP pdf. Perhaps this saves some other folks a bit of what I have gone through:
I would have to take another look at it when I'm home.
Ok, found it. I looked into an old thread of mine: https://budgetlightforum.com/t/-/25476 and the driver of the LZZ-06 is even 13mm (press-fit), I got it all wrong, I remembered that the driver that I used was a mm too narrow, but it was a 12mm board that I used, not 10. Sorry Richard for doing the work, I promise that will keep looking out for a 11mm driver flashlight to build this 11m board in .
