Boost driver

0.8-1.7 V 1 1x AA  

800 mA

 20 17 mm single layer, old version was 16 mm Boost driver, 20 modes in three groups. Output voltage and current not constant, 1.0 V in gives ~300 mA out, 1.4 V in gives ~700 mA out. Run on two fresh NiMH it outputs 1.8 A and gets very hot - not advised. I believe this is identical in operation to the AAA driver except for physical size (and the new version of this board is black). "LDCH" on the back of the board is the manufacturer.

Tip: To disable modes see this post.

Boost driver

0.8-3.3 V
(old version 1.5-4.2 V)		 1   41-86%

970 mA

 1 17 mm (not 16 mm) Boost driver (uses 2106F regulator chip). Reliable test data is hard to find and is complicated by people using different wiring methods. Some results are here and here but in the latter test, as pointed out, the output voltage dipping while the output current still climbs does seem a bit hard to believe. Discussion thread here.

Tip 1: It seems that modifying the set resistor to give a lower output current (max 500 mA) is a good idea.

Tip 2: Different wiring methods may give different efficiency figures.

 1 16 mm Version 4: As of April 2010 buck drivers are being sent instead of boost drivers. Buyer beware. Update: Product is sold out.

Version 3: As of August 2008 there seems to be a new version which may have different components and may not cope with anything over 3.0 V.

Version 2: Boost driver using Zetec C300 control chip, no capacitors. 100~700 mA output, dependent on input voltage. Test data discussion (in which various people point out the test data is wrong).

Version 1: 15 mm diameter.

Nanjg 18

DealExtreme

$4.26
(sold out and/or discontinued)

Boost driver

0.8-7.0 V 1 1-2x NiMH 60-91%

1000 mA

 17 17 mm Former version 19 mode Nanjg 16 (NJG-016) is the one pictured on DX. New version (NJG18) has the first mode group with just low, medium, high as detailed here.

Previous version: 19 mode boost driver using "Seiko S-8352D (or a clone thereof)" (datasheet, PDF 528 KB) which is a constant voltage boost driver chip. User-adjustable output voltage (not current) ~2 V up to 7.4 V. Output voltage must be greater than input voltage; one report says it will keep working down to 0.3 V but will not turn on unless input voltage is at least 1.1 V. Note that it runs out of regulation, so is not a constant current or constant voltage driver. Capable of ~700 mA output from a single AA NiMH cell, or ~1000 mA from two. Efficiency in the 60-70% range if output is much over 1 W (running the board on 1x AA), and pushing 90% at ~1 W - amazing for an inexpensive boost driver. Do not operate without a load connected.

Is it suitable for a Li-ion cell? See a good analysis here by Tido, who writes: "Yes and no. It's possible to use this circuit with a high Vf LED like an XR-E... Things are different with an XP-G..."

Tip 1: To disable modes (and a mode list) see this post.

Tip 2: A mod to get this driver to fit an Ultrafire A10 is detailed here.

NOT suited for 3x NiMH or Li-ion		 77-89%

630 mA
constant current

Can be modified to 1000 mA

 1 17 mm Constant current boost driver with either PAM2801 (max 350 mA) or PAM2803 (max 1000 mA) or J1JD (?) chip. Latest version outputs 630 mA; originally set to 380 mA. Claimed variable output current depending on input voltage, 600 mA (with 1.5 Vin) to 1.2 A (with 4.2 Vin), which makes me wonder what on Earth DX means by "Fully regulated circuit design"; those figures obviously aren't. However, testing by Hilarion showed perfectly stable current output from 1.2-3.2 V; very nice, although only 360 mA. Output current is determined by a sense resistor with 95±5 mV feedback voltage. Thus 0.25 Ω sense resistor as supplied in 2009 gives 380 mA, 0.15 Ω as presently supplied gives 630 mA, 0.1 Ω gives 950 mA (measured 900 mA at ~80% efficiency). Efficiency is said to drop horribly with input current > 2 A.

As pointed out in this thread there are no components to buck voltage as implied, so it would actually be direct drive when Vin is greater than Vf of your LED.

Boost driver, possibly Seiko S-8352D boost chip. Uses PIC12F629 microcontroller chip for modes, probably with an AMC7136 (sic) linear regulator (datasheet, PDF 954 KB) for dropping small excess voltage as well. 5 modes: High (1,000 mA), mid (350 mA), low (50 mA), strobe (1,000 mA), SOS (1,000 mA).

Version 2, TR-0055C or TR-5055C: Has a slightly smaller inductor than the previous version and uses the FP5138 regulator chip. Output is set to 650 mA.

Version 1, TR-0055 or TR-5055 or TR-0055a2 or TR-5055a2: Has a lovely big-looking inductor and uses the AS2001 regulator chip.

5 modes, with memory - high, medium (56%), low (26%), fast strobe, SOS. Test results here or here by EpRoM which includes a 30 minute test at 12.44 V. Voltage across sense resistor is 0.5 V.

Tip 1: An investigation into eliminating the flashing modes is here (for single mode mod see post 11 and pic in post 13).

Tip 2: Operation with >12 V input may need a resistor changed, and for running 6 LEDs the output capacitor may need to be changed - an analysis and discusssion is here.

 1 12 mm x 8 mm x 7 mm Can be used as either a buck, or boost, or buck/boost driver - see the Application Notes for connection diagrams and other info. Not a constant current output; they claim this is a design feature to mimic the light dropoff of an incandescent bulb. I'm not convinced. Maximum 8 V output. Can be used in parallel. Efficiency as a boost driver claimed 70-82% (measured at 64-78% in a test with an XP-G here), as a buck driver 82-89%; as a buck/boost driver 62-72%. The datasheet doesn't claim an IP rating but does say "The 2009A is encapsulated by an insulating epoxy and is resistant to harsh environments and moisture."

 1 19 mm Boost regulator. Maximum input current 4 A, said by manufacturer to be still efficient >3 A. Regulates on voltage or current, output current adjustable from 50-980 mA (or greater by changing set resistor, although that would remove load protection) at maximum 32 V. Includes copper heatsink; improved thermal performance and higher output voltage over standard Shark.
 
I note that Wayne here recommends new buyers to get three.

Notes

Footnotes & Instructions

  • Video Foundry/Aqualab does not sell any of these drivers. Links are provided to resellers.
  • Use the pop-up menus, check boxes, etc, in the second row of the table to filter the results.
  • Click on the links in the titles in the top row of the table to order the results by that information.
  • Results of searches can be bookmarked because all the search parameters are contained in the URL. (You can delete the parameters you don't want - for example, http://www.videofoundry.co.nz/ianman/laboratory/research/driverlist.php?sku=26110 brings up just that driver.)
  • All prices in US$ (except where dual prices are listed in US$ and € for some European retailers).
  • All driver boards from DealExtreme and KaiDomain include shipping.
  • Information is unfortunately not guaranteed to be correct. any updates, corrections, omissions, etc.
  • However, please don't bother sending me an email to tell me about your company's LED products. It will be treated as spam. I really don't like spam, and SpamCop is busy enough as it is without having to process your email as well. Putting "Re" in the front of your spam's subject does not make it any less likely your spam will be sent to SpamCop.
  • Recommended drivers highlighted in green. They have a good combination of price, features and efficiency.
  • Drivers no longer available (sold out or backordered) are highlighted in grey.
  • Recommended drivers no longer available are highlighted in a darker green.
  • Drivers listed at those resellers as "Backordered" etc for more than a month are deemed to be discontinued (although I'm happy to later be proven wrong).
  • Don't connect drivers that have capacitors across their outputs to LEDs while the driver is powered. An explanation (on CPF) why not.
  • No mains driver will be completely waterproof. Those that are water resistant mostly have an IP rating (eg, IP67).

Notes on Schottky diodes (click to expand/contract)

Schottky diodes are diodes that have a low voltage drop across them. 0.3 V is a typical figure, compared to around 0.60-0.65 V for a typical silicon diode. This makes Schottky diodes good for rectifiers and LED drivers where high efficiency is required. Drivers that use the AX2002 such as DX 3256 can easily be modified for higher output current but the Schottky diode needs to be replaced if the output current is to exceed 1 A.

Inexpensive Schottky diodes are available from these sources:
