LED Driver List – all LED drivers

An O-ring, Tailcap & Silicone Grease List is also available.

Video Foundry/Aqualab does not sell any of these drivers. Links are provided to resellers. The short URL for this list is www.videofoundry.co.nz/driverlist. See the bottom of the page for my email address. If you're just a spam bot looking for fodder, spam the hell out of these spammers' addresses: spammer address 1, spammer address 2, spammer address 3. They deserve a taste of their own spam.

Note that some sellers are more reliable than others. Inclusion of particular resellers in this list is not an endorsement of them as businesses. Note that Fasttech closed in December 2022 but the drivers are still included for reference.

 1 42 mm x 32 mm x 12 mm The URLs linked below have all been reused for various LED products, but the drivers may still be listed on their site elsewhere. Good luck finding them.

Incomplete specifications on manufacturer's and retailer's web sites (incompetent manufacturer?); output voltage/LED quantities unknown. However, by using the wizard on the manufacturer's site it appears they'll do 1-4 LEDs. The claimed maximum 91% efficiency is very good, if true, especially since the drivers (except the 1,400 mA) have a rectifier built in. Even if maximum efficiency is up there however, it's probably not representative of typical efficiency, especially since they all claim the same (except for the 500 mA version which claims 92%) - unlikely across the whole current output range. Soft start. PWM dimming with 0-10 V input or potentiometer. Available in versions with outputs of 350, 500, 700, 1,000 and 1,400 mA.

 1 17 mm x 6 mm high Update Feb-Mar 2015: Buyer beware - DX has posted new photos which shows the same driver as FT sku.1105800. The claimed details are no longer correct; this driver is sadly no longer recommended. Also, the output current is no longer constant, varying from 820 mA with one LED down to 600 mA with three LEDs in series. This a a very sad change.

Update Nov 2009: New version using AX2002; now constant current output with 0.27 Ω set resistor, slightly larger diameter. Overhead is ~0.52 V. Test data and discussion here.

Tip: The output current can be increased (or decreased) by changing the set resistor appropriately (Rset = 0.25 / current) but the diode is a Schottky SS14, which has a maximum current limit of 1 A. Inexpensive 3 A Schottky diodes are listed here or here (if you want to risk that site).

Old version: 16 mm diameter. The details still on the DX site are for this version. Buck regulator using Zetex C310. 800-1000 mA output dependent on input voltage, although a hack for lower output is explained here. When run at lower output it appears reasonably constant current regulated. Test data graph.

Wiring harnesses are also available, with and without potentiometer for trim adjustment. An additional capacitor across the input may be needed to smooth input power, as described here.
 
This retailer (3023; wired version) has good prices and a driver selector tool to help sort out all the varieties. Good luck.

 1 17 mm November 2011: The present Kennan may be version 4; input voltage range previously claimed to be 3.6-23 V, now 4-18 V. It's still a good driver but it's more expensive than it needs to be, so no longer recommended. Consider KD sku S009736 or DX sku.26110 instead.

Buck regulator based on AX2002 chip. Constant current output, off the shelf set to 1 amp. Efficiency figures from AX2002 datasheet, but "AX2002" test results I've seen that may be of this board indicates 78-87% for a single LED below 1.4 A, sagging to 65% at 2.4 A.

Note: In italianboy's review (apparently lost with the Nov 2011 KD site update) he claims that 1 amp is outside the driver chip's limits. This is not true as the AX2002 can actually cope with 2.5 amps, although it will get very hot over 2 amps, meaning without heatsinking the thermal protection will probably turn it off after just a few minutes. Also, the other components on the Kennan 3 board may not be too happy at 2+ amps; the Schottky diode is an SS14, which has a 1 A limit.

The Case 1 and Case 2 examples mentioned on KD's site mention the 750 mA that an earlier Kennan driver was set to.

Input variously listed at 5.5-15 V (with <12 V preferred), 5.5-13.2 V, and 4.0-12.0 V. 90-95% efficient seems to be the default claim by this retailer. The claim to provide 1+ hours of 3 A output from four Eneloop cells is clearly false for a Cree MC-E or SSC P7. With a LED Vf of 3.4 V (MC-E) that's 10.2+ Wh output from less than 8.5 Wh input (Eneloop @ 2.25 A, assumed driver 95% efficient for estimating battery voltage under load). This also raises doubt about the constant current claim. Buyer beware.

 1 54 mm x 26 mm Apparently a voltage-controlled driver with the output voltage set using a potentiometer; output voltage 1.5-22 V (use that potentiometer with care). There's an implication this driver should be used with a resistor in series with the LEDs. Claimed "max 700 mA, peak 2 A" is contradictory. Built-in rectifier for AC or DC operation. Unknown operation method but thought to be a linear regulator because of the presence of a large heat sink on the board.

 1 17 mm double sided board (formerly 19 mm) It's hard taking KD's site seriously when so many random colours and sizes of text is used to describe the board, with missing graphics liberally distributed as well. (The site has since been updated.) Inconsistent specifications, with output current listed as 2.8 A and 3.0 A and input voltage listed as 5.5-15 V and 4.0-12.0 V. Three mode; low (5%), high (100%), medium (35%) - also listed as high (2.8 A), medium (1.38 A [49%]), low (0.25 A [9%]). The runtimes given don't stack up. There are two versions (with 3 and 5 modes) which look identical and either might be sent to fill an order. Buyer beware.

This driver gets a bad review here. StefanFS here says it gets really hot with 8 AA cells, while CM here calculates over 2 W of heat dissipated in high mode - toasty - while showing the claimed 90-95% efficiency is imaginary.

Appears to be the same as e-lectronics sku 464.

 1 18 mm x 14 mm x 11 mm (31 mm x 18 mm x 11 mm including prongs and output terminals) Buck regulator based on PT4115 chip and Schottky SS14 diode. Earlier version EQB8L chip. They're not quite equivalent as the PT4115 will turn off under 8 V and the EQB8L will work under 4 V (voltages not including the rectifier on this driver). Maximum voltage listed is from max rating for output capacitor. Constant current out 650-700 mA. Built-in rectifier, normally four Schottky SS14 diodes.

The PT4115 version is said to be quite good with one and quite good or excellent when driving two or more (unfortunately the test results to which I had linked have been withdrawn pending further investigation). For automotive use (~12V) the EQB8L version of this 3 W driver is not very efficient when driving only one LED, but quite good with two (84%); thus the EQB8L seems better suited to lower currents with single LEDs. There are a couple reports of this version emitting RF noise causing interference with car radios and remote locking, but most users haven't found any interference.

There are MR16 sockets available for them - round (17 mm diameter) and rectangular (28 mm x 17 mm).

Tip: If using DC and sure of polarity you wouldn't need the rectifier so you could short that out for an extra 4-6% efficiency gain, but it will still work with it left intact.

These drivers have their own bridge rectifier using low-voltage Schottky diodes, so they can handle (low voltage) AC or DC input. While these drivers are claimed to handle 12-16 V AC, the PT4105 is only specified to handle up to 18 V input, so allowing for perhaps 0.4V drop on each of two Schottky diodes being used at any time in the rectifier, anything over about 13.7 Vrms AC would be outside the PT4105 spec.

Large input voltage range (the minimum input voltage of 1 V is assumed) but input voltage must be at least 1 volt above output voltage and a maximum of 10, 10, 7, 5, 4, 3, 2.5 or 2 V above output voltage for the respective versions. The mention of PWM is believed to mean this driver can be used with a separate PWM driver, not that this driver uses PWM. Has thermal protection and output short circuit protection.
 
Also available in non-SLIM versions which have a heatsink, allowing better heat dissipation and wider input voltage tolerance.

 1 17 mm April 2011: AX2002 driver chip used again (which has a minimum input voltage of 3.6V in its specs), with SS34 Schottky diode and 0.2 ohm sense resistor. (Add 1 ohm resistor in parallel to increase output to 1.5 A.) The input capacitor is said to be only rated for 16 V. Red board. Or green board (my very next order just after getting a red board). See AX2002 footnotes for using as a voltage regulator.

November 2010: This driver may have changed again, with the YB1682 voltage regulator chip being used. Not good.

Previous version (Feb 2010): Regulator chip AX2002 with 0.2 ohm sense resistor gives output 1.25 A, and the SS34 Schottky diode is great if you want to bump up the output current. DX's description claims it provides different current outputs (1-1.2 A) to different Cree efficacy bins. I think NOT. Tests with the previous version showed a constant 1.10 A, which was very close to the theoretical 1.13 A of an AX2002 with the then 0.22 ohm set resistor. When multiple drivers are used in parallel the efficiency apparently drops, probably because one driver is doing most of the work (and so gets quite hot). Hence, these drivers should probably not be run in parallel.

Every so often the regulator chip changes, and in the case of the AX2002 had its identifying marks removed. This is quite frankly silly, as DX's customers went through another round of not only figuring out what the specs for the board were, but working out what the new chip was as well, before they could figure out the board's specs. The driver chip was suspected by some to be MC34063A (not an obvious choice by any means as the chip isn't pushed as an LED driver and the claimed similarity to a certain reference design doesn't exist), YB1682 (has a different reference design - not surprising because it's a voltage regulator not a constant current driver), PT4105 (unlikely because production of that chip was terminated before this board was listed), PT4115 (unlikely because of reported working voltage range) or AX2002 (perhaps most likely; the board appears to be the reference design except for choice of some components, and my chip has part of an A still showing).

Tip 1: The output current can be increased (or decreased) by changing the set resistor appropriately: I(LED)=0.25V/Rsense. The diode in the product pic is a Schottky SS24, which has a maximum current limit of 2 A, but as of Feb 2010 are shipped with a Schottky SS34, with a 3 A limit. The AX2002 driver chip has a 2.5 A limit and gets very hot over 2 A.

Tip 2: Maximum efficiency is achieved when running multiple LEDs from one driver with just a few excess volts (eg, 4 LEDs with 5 Li-ion).

Notes on AMC7135 linear regulator (click to expand/contract)

The AMC7135 (datasheet) is a linear regulator, which means it acts like a variable resistor changing its value to try to keep the current constant. Like a resistor, any dropped voltage is burnt off as heat. Boards include a polarity protection diode and can easily be PWM-driven for lower modes.

Vin must be at least 0.12 V above Vf of LED to stay in regulation, although they drop out of regulation quite gracefully, not suddenly. The graph in the AMC7135 datasheet (Jan 2006) has the 0.1 and 1 volt vertical lines missing. Each AMC7135 provides constant current, about 1/3 amp (actually 300-380 mA depending on particular version; I've generally assumed 330-335 mA for above listings). Boards come with one to eight AMC7135s, and single mode up to 20 mode. Boards can be paralleled to give greater output, or connected with one multimode board controller providing the modes for several boards.

The AMC7135 is very efficient when input voltage is close to output voltage but not particularly good when input voltage is significantly higher. Average efficiency for 3x NiMH or 1x Li-ion can be well over 90% with an LED with the right Vf. Test results and discussion for 3 and 4 chip boards.

Since the AMC7135 just burns off excess input volts as heat, the more volts fed into them the hotter they'll get. One guy claimed that his got so hot they slid right off the board (ie, >183-190 °C melting range of 60/40 solder). The AMC7135 has built-in thermal protection (which will cause dropouts or a flickering effect if it gets too hot) but the multi-mode control chips used on the multi-mode boards are much less rugged. (And here.) If using with an input voltage above 4.5 V or so you can expect them to get hot!

To get multiple modes typical microcontrollers used are the Atmel ATtiny13 (or 13A or 13V) and the Microchip PIC12F629. These both have a 5.5 V maximum, while the AMC7135 linear regulator has a 6.0 V maximum. This means that multimode drivers will have a slighty lower maximum voltage than single mode boards.

Tip 1: To get reliable operation at low voltages, especially with only one AMC7135 chip being used, you may need to short out (and maybe remove) the polarity protection diode(s)*. This is because the AMC7135 in series with a polarity protection diode needs a minimum 2.7 V + 0.6 V (silicon diode) = 3.3 V to stay in regulation. The Vf of LEDs at 330-350 mA can easily be quite a bit lower than 3.3 V so will not be running in regulation. Note that if a germanium or Schottky diode was used the drop could be as low as 0.3 V instead of 0.6 V.

* However, I found with one multimode board this caused the board to go unstable (don't know exactly why) but I found that inserting a small value resistor instead of the diode was enough to get the driver stable again. Because the drive current through that point in the circuit is so low (6 mA for mine) there's very little voltage drop across the resistor - much less than across the diode - so it still serves the purpose of saving ~0.6 V.

Tip 2: If the input voltage is too high you may be able to use another LED in series with the board to drop the voltage - it beats burning it all off as heat. (The set current is <1 mA for single mode boards so both LEDs will get practically identical current. Diagrams and much discussion of use with multiple Seoul P7s and multi-mode boards.) More than one extra LED appears to be not a good idea for use with the lower modes of multi-mode boards since the Vf of the extra LEDs decreases too much at the low current to protect the driver from the battery voltage. (Many of the multi-mode boards have a capacitor on the output.) Flashing modes appear unsuited to this technique.

AMC7135-based driver options are discussed here, or an inexpensive multimode AMC7135 driver here.

Notes on PT4105 and alternative driver chips (PT4115, AX2002, CL6807) (click to expand/contract)

PT4105 (datasheet):

Production of this driver IC - as used in the Kennan and MR16 base drivers described above - has been terminated. The manufacturer doesn't even have a publicly displayed link to the datasheet any more, which is the weirdest part of it. This from Micro Bridge (now removed from their site; try to ignore the punctuation and spacing):

The PT4105 which the manufacture has already officially stopped producing,and the subsequent instead item is the PT4115,AX2002 and FP6101 Also,The PT4115,AX2002 and FP6101 has superior performance over ,wider input range and more current than the PT4105.

PT4115 (datasheet):

While I look forward to the PT4115 being available in low cost LED drivers (by its numbering the apparent successor to the PT4105), I note that it needs an input of at least 8 V (and has under voltage lock out at 6.8 V), so isn't nearly as well suited to low voltage torches as the PT4105 was. It will, however, have its uses for 3x Li-ion torches and automotive purposes. The chip has a DIM pin which gives it the ability to very easily be dimmed. Efficiency is about 80-82% for 1 LED, up to 93% for 3 LEDs, and apparently up to 98% for 7 LEDs. Maximum output current 1.2 A.

AX2002 (datasheet):

This driver chip from AXElite looks extremely interesting. It will accept a minimum 3.6 V input and has a maximum switched current of 2.5 A, although it tends to overheat at more than 2 A. It includes thermal protection (140°C), over current protection, short circuit protection, and has a PWM control circuit. Its efficiency is good too, with an output of 2 A @ 5 V it's an impressive 91% efficient (with 12 V input). Driving a Cree XR-E at 1 amp will give an efficiency of about 87-88% (with 12 V input). Efficiency is not quite as good at low currents with a single LED, dropping under 80%.

AX2002 drivers can also easily be configured as a constant voltage power supply. The load is connected straight to ground and the 0.25 V reference voltage is used to control a voltage divider with a couple of moderately high value resistors to give a fixed multiple of 0.25V at VOUT.

For example, for 5 V, 5 = 20 * 0.25, so a 10 kΩ resistor is placed between ground and FB (the feedback pin), and a 190 kΩ resistor between FB and VOUT (making the total of those resistors between VOUT and ground of 200 kΩ).

When used in this way, to give stability the current through the resistors probably just needs to be comfortably greater than the feedback pin bias current of (0.1 µA typical, 0.5 µA maximum). If two exact resistor values for the voltage divider are not available it's easiest to use a single resistor for the sense resistor (between ground and FB), while the other value (between FB and VOUT) uses two resistors in series or parallel. For series, one of those two resistors will be as close as possible to the desired value, and just under it, while the other will be a much smaller resistor to tweak the total resistance up for the output voltage wanted. For parallel, the main resistor is just over the actual value wanted while the other resistor with about ten times the resistance tweaks the total resistance down. If that resistor is getting into megaohms you should probably revise your values.

Some AX2002 drivers (such as DX 3256 sadly no longer an AX2002 driver) come with a 1 A Schottky diode, which will need to be changed if increasing the output current over 1 A. See the Schottky diode notes below for links.

AX2003 (datasheet):

The AX2002 also has a big brother, the AX2003, which has a maximum switched current specification of 4 amps – easily enough to drive a Seoul P7, or a Cree MC-E with the dice in parallel. No drivers with the AX2003 are presently known. The spec sheets of the AX chips could do with a few more graphs showing how constant the output current is, etc.

FP6101 (datasheet): Not an LED driver.

CL6807 (datasheet):

Chinese LED driver, 1 A maximum output current, 6-35 V input, 0.1 V high side sense voltage. Claims to be able to provide up to 35 W output power. Dimmable with 0.5-2.5 V PWM signal.

So there are some nice driver chip options, but it still leaves a gap of a high efficiency, really low voltage, low current driver.

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:
