  • Efficient and robust FP5138 boost driver

    posted by desolder on 14:16:17 G5T 27/05/2011 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: This is a boost driver for when you need to increase your battery's voltage in order to drive multiple LEDs in series. I am using it to drive 3x sku.4516, for a total output voltage of 19.8V. The power source is six 18650's wired as 3S2P (11.1V). This is for my primary bike light, which I guesstimate outputs 1000 to 1200 lumens.
    I am getting about 80% to 85% efficiency, which is very good for a boost driver.
    Check out the CandlePowerForums thread which discusses this driver. You can adjust the output current and modify it to exceed the 8.4V input limit. You can also disable the modes, which I have done.

    Cons: This is a much larger driver than most typical flashlight drivers, so be sure it will fit in your project.
    It gets very warm, so you may need to heatsink it.

    Other: This is an absolute steal for four dollars!

    Involvement Level: Expert (understands the inner workings)

    Pros: This is one of the few boost drivers on sale. I prefer boost drivers because generally they allow the use of higher capacity 18650 batteries in place of 16340 batteries. This is a CC driver so should, in theory, work with less than 5 LEDs in series - provided there is sufficient voltage differential. I'm planning to use this driver to replace the buck driver in my MX Power 3xCREE flashlight SKU 5971 - provided there is room in the pill for it. This should allow the use of 2x18650s in place of the 4x16340s.

    Cons: Others have reported that the driver gets quite hot.

    Other: Very cheap high power boost driver.

  • Simply too hot!

    posted by littlegiant on 10:16:40 G7T 20/07/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Good Price
    Easy to use
    5 mode
    Able to handle 2 li-ion cells

    Cons: NO memory
    Simply too hot.
    Low Efficiency of 67.5%. 7.4V input (8.6W) only results in 1.845A @ 3.15V output (5.81W). This means that 2.79W of energy will become heat in the driver which makes the driver heat up really bad within seconds. I couldn't put my finger on the driver for more than 2s after 20s on high. I wouldn't recommed this driver in any torch light unless you like a torchlight that can warm you up.

    Other: Good for testing but don't get this driver for your torchlights. Too hot to handle.

  • Better than I thought it would be.

    posted by Forgiven on 22:23:49 G3T 31/03/2010 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Driver seems to be well built. Its very easy to use, and on 6 nimh cells it drives 5 XRE R2s well. It was brighter than I thought it would be on high.

    Cons: Strobe and SOS

    Other: This is the only cheap boost driver I know of that will drive 5 leds on 7.4 volts. This was the easiest multiple emitter light I ever made.

    posted by googy on 07:23:36 G9T 15/09/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: The only driver on DX capable driving 4-5 LEDs in series from 5 - 8.4V.
    800mA are better then 1000mA, because of 15W power, 80% efficiency and no thermal management

    Cons: no thermal management (except the coil)
    driver is getting warm-hot

    Other: useful and cheap driver
    2xLiIon / 5xNiMh / 6xNiMh

  • Great D. I. Y. project.

    posted by pault on 20:44:44 G7T 29/07/2009 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: Great for D.I.Y. project 5 mode driver.
    Good range for Cree emitter from P4 to Q5.
    Boot up the voltage up to more then 19 volt. ( Test on a electronic meter )
    Good range from battery power up to 8.4 voltage include Li-on, Nimh and Alkaline etc.Include rechargeable battery.
    Test with 2 pc. 16850 3000mah battery, more then 50 minutes on high mode.
    With memory function.

    Cons: None so far.

    Other: Wide range 5 mode driver for project from DX.
    Highly recommend for L.E.D. fans. Buy more for D.I.Y. project spare part.
