As more DIY drivers become available it is becoming significantly harder to select the right one for project if you are not following the thread constantly.
If I may suggest organising drivers by led type they are meant for or by input voltage, led voltage and led current!
Then, when someone is trying to find 2S cell driver for MTG2 led, he can do that quickly…
The organization, such as it is, is based loosely on driver type and then size. There’s a fair amount io duplication now but I have no wish to delete links without a request from the author or notification of a nonfunctional link. Many of these drivers are used for many different LEDs often with different voltages and all you do to use a different voltage led is look for where to put the Zener diode and 200 ohm resistor. It can certainly get overwhelming and reorganization is not unlikely but it’s assumed that if you have a question you will ask it and it will get answered. Most authors are good about starting threads to discuss the finer points so that such details aren’t buried here but it still happens. Such is the internet.
If someone would like to assume responsibility for this thread, change the format to table form, or whatever. I’d be happy to copy the entire OP in edit mode and send it as a pm. You would then be able to start anew with a blank thread. Maybe SB could figure out a way for another member to access/edit the op instead. IDK.
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:
