New linear drivers @ kaidomain: 4x, 6x, 8x7135 (was 2280mA driver "programmable")

Flashlight Modding and DIY Parts

But if you strip those extra chips from the 8x7135 version, you can use the spare chips to build 3500mA drivers without buying more

22

True, but I am always looking for different drivers to experiment with. I wonder if that's a ATiny13a on that board it hard to tell from the picture?

23

4x7135 and 8x7135 drivers now available (and just ordered :-) )

24

Ordered the 5 pack ....

Need some emitters now ...

25

26

If you look intl-outdoor website you'll see they have single AMC7135 chips, actually rated 340mA-380mA. So, 380mA x 6 = 2280mA

27

True, and HERE is the link for a single unit

Here are some other new drivers at KD:

1-4XML 3-18V 24mm and 6-15V, 1-9A Current Selectable Circuit Driver

28

Has anyone tested yet?

Mine arrived today. Too bad no time to solder and test any yet... :(

29

Mine are still in the pipeline...

30

Is there any way you can tell if the control chip is a ATtiny13? Could you take a close up picture of the board?

31

I Googled for the ATtiny13 picture and I have to say can´t really tell.

That component on board is pretty well sanded down :| no markings, can it be still identified?

32

I don't know how to tell without seeing the markings, thanks for looking.

33

I had two delivered a few days ago but also have no time atm. to try them out. The MCU is completely without markings, but I used an Ohm-meter to clarify the connections and I can say that the MCU is definitely not atTiny 13A (sorry!). It is connected more like the 12F629.

pin 1 to plus and pin 8 to ground. Output to 8x7135 38K (hence the multible of 380 mA!) is pin 3. Low battery sensing (from resistor divider) is pin 7 and the 4 inputs from four soldering pads are pins 2,4,5 and 6. Perhaps someone can identify the family from this?

The protection schottky diode is marked S8 (that is normally S6). The circuit board is marked: L3AD4S.

Hi everybody… Happy New Year…

Anyone know where I can get some bare amc7135 380ma ? Thanks

35

You can get the 350 ma bin from here, not sure about the 380 though.

37

Hi Scaru, I find those minutes ago, I am waiting responce from there if their can get the 380ma model.

I was looking something cheap… :smiley: Thanks

38

the post you dug up is over a year old....

39

Yes, I know, I preffer to continue a old thread than open a new with the same concern. Thanks for let me it know. Happy New Year
