The last image is from after my test.
Driver is from Fasttech.com
Official specifications


  • Operating Voltage: 3-4.2 -volt
  • Output Current: 3000 mA
  • Flashlight Modes: Lo > Mid > Hi
  • Mode Count: 3
  • Mode Memory: Yes
  • Cable Length: 3 cm
  • Depth: 3.5 mm
  • Height: 17.5 mm
  • Width: 17.2 mm
  • Max. output current: 3A
  • 3-Mode: Low(80mA) > Mid(700mA) > Hi(3000mA)

Measurements


  • Diameter: 16.8mm
  • Height: 3.4mm
  • Driver has memory.
  • A short off/on selects next mode.
  • Driver uses linear regulation.
  • The modes are 85mA, 0.9A, 3A
  • Double click for strobe.
  • There is battery warning below 3V

Test is with XM-L led
High
Fasttech4594600%20High
The driver can maintain full output until 3.5V, then the output starts dropping.
Being a linear driver the input and output current is the same.
Fasttech4594600%20HighDriver
Power loss in the driver depends on difference between led voltage and input voltage, with a fresh battery it may be around 2 Watt.
Fasttech4594600%20HighLed
With 3A to the led the output power is around 10W
High4V
No PWM, only a bit of noise in the signal.
Blue line is voltage across led and yellow line is brightness measured with a photo diode.
Temp5788
M1: 109.1°C, M2: 130.1°C, HS1: 165.6°C
But the driver needs cooling when running in high, this was less than a minute with 4.18V in, i.e. about what a fresh and over charged battery may deliver.
Temp5789
M1: 81.6°C, M2: 103.9°C, HS1: 117.5°C
Dialing the voltage down to 3.88V reduces the heat some, this is again after a minute and a good battery can keep above 3.9V for 10 minutes!
Warning3V
The battery warning signal is fading off/on every 3. second.
Medium
Fasttech4594600%20Medium
At medium the output can be maintained down to about 3V
Fasttech4594600%20MediumDriver
The power loss in the driver is up to 1 Watt
Fasttech4594600%20MediumLed
Power is about 3 Watt
Medium4V
Again the signal is smooth without any pwm.
Low
Fasttech4594600%20Low
At low the output can also be maintained down to 3V. When the low volt battery warning is activated the current drain increases.
Fasttech4594600%20LowDriver
Not much power loss in the driver at this low current.
Fasttech4594600%20LowLed
The led gets about 0.25 Watt
Low4V
Without any PWM.
Strobe
A couple of fast off/on will activate strobe, it is 12Hz with 50% duty cycle
Fasttech4594600%20Strobe
The led current is 3A in 50% of the time when in strobe mode.
The efficiency and current in curve is wrong for this mode.
StrobeCurrentLed
StrobeCurrentPS
Just to verify the current I used my current clamp.
Strobe4V
Conclusion
This looks like a nice linear driver for 3A leds from a LiIon battery, but it need good cooling on the mosfet transistor when running in high mode.

Thank you for the test.

I like this driver, but I do not like memory: is there a possibility to do the “pencil trick” on one of the capacitors to remove memory and let the driver start in low all the time?

This is LD25 driver, which is “also available from Simon store:
https://www.aliexpress.com/store/product/Free-shipping-LD25-Flashlight-circuit-board/

All modes are programmable (except for strobe). Recently it arrived to me and I already checked. Works great.

There is another layout on the movie. I marked the programming (set) pin in red.

Hope it’s useful Smile

Thanks for the review. HKJ. I’m sure a certain member will be very happy with your results.

Also thanks to Chatika vas Paus for the video, can you also reduce current in each mode?

Reducing current you need to tab the red wire to brass ring and if you hold it will increase current.

ordered this driver 2 weeks ago. cant wait to get my hands on

Nice indeed. Used a few of these already, now I can understand why I had a hard time trying to measure its output flicker with VISO Flicker Tester.

MOSFET temperature speaking, once the driver is installed in a flashlight it is able to transmit heat to the host, thus its effective temperature should be considerably lower ( Question ).

Nice to see mode current can be adjusted, but I would certainly thank a more careful explanation besides what's seen in the video.

At last, let me say the driver has two track jumpers on the underside, one of them comes stock closed and the other is open:

 

In Chatika vas Paus photograph, the closed one is above, the open one below.

 

In this picture by me closed one is to the right side, open one at the left.

I wonder what do they do. 

 

Cheers Party

My driver from Simon arrived with open jumpers.
I asked about this Simon. His answer: it’s useless

Let's see if I understand how current can be set for a given mode. Initial conditions:

  1. Driver has an attached load (emitter).
  2. A way to determine emitter current is set up.
  3. Driver is powered with a voltage source beefy enough to overcome all burdens.
  4. Driver has adequate cooling.
  5. Driver mode to adjust is selected.

Then, when connecting the adjustment wire to ground driver will alternatively increase or decrease current until adjustment wire is ungrounded or some limit  is reached. Is this right?

I wonder how low can it go. 

 

Cheers Smile

A really detailed explanation would be great!
I do not know how far you can reduce the current but i see a sens resistor. And usually playing with it, in or decreases the current. Could be a last resort if the programming is not enough.
I increased the current on my TN31 (K40m driver installed) a long time ago by switching the sense resistor from 100 or 82mOhm original to 50mOhm. And when i turned it on for the first time i was thinking : it’s alive it’s alive. Huge difference!

Hey Barkuti

have you receive your driver yet?

I’m curious to know what is the lowest current it can go.

Nico -.-

I have 2 drivers. I think it’s highly depends on used led battery.
1,49mA with Jaxman LG led and Sanyo NCR18650GA
4,6mA with LH351D and Panasonic NCR18650B

thanks Chatika

so the driver can adjust the current for each mode?

5.6mA is true firefly and this is what im looking for Smile

Little mistake, already edited. Its 4,6mA, not 5,6.
Yes, each mode can be changed. Just select the mode in which you want to change the brightness and taptaptap (I recommend doing single/slowly taps) to reduce the current and hold for increase.

I noticed something strange. I have reduced the current of the lowest mode to about 35mA. After switching from Hi> Lo, Low it ramping from 0. It doesn’t work when turning on at lowest mode.

What does he said? Big Smile

Err, do you mean that, when switching from high to low, low starts ramping from 0 to your 35mA current setting?  How fast?

Fast, but it can be seen. Half a second, maybe less. At 60mA, I didnt notice it.

Adjusted low mode to 100 mA and sometimes I see ramping too. Also my driver had strange modes by default: med 1.1A, high 2.2A. However, “set point” works as expected and all modes adjustable.

Barkuti, in other threads you said high mode might be bumped up via the jumper – is this the case? Did you try, and if it works – how is it?

Better try this:

All modes are independently adjustable.

Heatsink the driver well.

How do I set the Mod I plan to change? By On/off the power source and leaving the driver memorized the mode?

And does the Simon ´s method works on new drivers from Fasttech?

You need to chose mode that you want to change. And tap, tap, tap or hoooold.
Yes, its works.

I didn’t think it would work with the new version.

This seems to be normal.
Mine do this too, even with stock settings.

So, can the current of the high mode be adjusted to values higher than 3 Amperes? Or is 3 Amperes the maximum?

3A is probably the maximum by design, to avoid onboard stuff burning out. But cooling can be improved, so time to stack additional sense resistors atop the stock  R010. Each R050 will allow extra +600mA, so up to 4.8A with 3x additional R050 sense resistors. I advice to install some tiny copper heatsink over the AON7520 MOSFET in such a case.

 

Cheers Party

P.S.: tried to use de simple post editor, Jerommel, but couldn't. The advanced one is WYSIWYG.

I guess i should have tried before, using the advanced post editor makes all the code invisible, so problem solved. Thumbs Up

But i ordered some sub Ohm resistors to slap on top of the R010.

R020 on top should get me 4.5 Amperes. R030 should get me 4 Amperes.

Waiting for them to arrive...

Where to get cheeeap low value sense resistors? I have a few R050s, R200s and others scavenged from drivers, power bank boards, etc.
