I would love to know this as well. It seems that 1100mA works, and I'm looking for something that can buck and boost at 1.5A for a 445nm LD from a Vin of 3.0-8.4V. I've been looking all over the place for something like that, and the flexdrive is the only thing that comes close.

At least not with batteries as the power source.
Ok, that's cool. I don't think it was until recently that they added the diode and capacitor to the datasheet. Before, they were touting the "no external compnents needed" line.

Alas, so I hear. I was hoping to run this off a single Li-Ion, but I guess I'd need a boost driver to do that if these 445nm diodes are 4.2V Vf.

Current draw of the circuit will be determined by the regulator. If you plan to use 3 7135s it will be ~1 amp at the diode no matter where you put it in the circuit. To keep below the max supply voltage of 6V will require 4 diodes, but battery voltage will sag quickly so you can get away with 3. E*I=P so 2.1*1=2.1 watts turned to heat in the diodes.

I don't know if, or when the datasheet was changed to include that, but there are different datasheets, as well as different makers of the IC, both Taiwanese and Chinese. The micro-bridge one I don't see the output cap. Addtek has it in theirs. LPF user Renno reports here having trouble with output cap but no details of what capacitance he tested. Or if he put it to ground.

Depending on drive current, yes. You could try a GD1000 but max Vin is only 5.4.

Default Re: Drivers for 445

I have done no tests but I guess >1000ma

regulating that much current generates heat

and sinking the driver will make it work better

The flex is the way to go, why limit yourself

Default Re: Drivers for 445

Everybody seems to think the flex is the best way to go. I'm curious why the microboost isn't a better choice. I've been thinking of using a microboost with a single li-ion. If the flexmod would be a better driver for me, could someone explain why?
Thanks

They both work good... I've been using mostly the Micro BoostDrive for up to 1 Amp. And 1100mA's by one request...

But the same for the FlexDrive. I have set it at 1100mA's too. (by request)

Default Re: Drivers for 445

So just to double check, you can't use a microboost maxed out w/ a RCR123a correct? The RCR123a wouldn't be able to put out enough current?

And I don't think I read it much but I'm using a LM317 in my POINTER - yes, a pointer i made which uses 3x 18650s and the LM317 circuit is set up to 1.25A

Edit: Also, I have another quick question if anyone can answer. Can I just set the microboost to the highest range setting and then turn the pot all in one direction without having to use a test load? Like, I'm guessing the pot stops and so which direction do I turn it for max? As you can tell, I never used one before, and only used a flexdrive v2 once a longg time ago.

It just depends on the quality of the battery I think...

Plus the capacity is a big concern at high current demand...

I just set and tested a V5 FlexDrive at max... 1.5 Amps.

An RCR123 did not hold current. Nor did a 14500. But an AW 18650 held steady...

Hi. Jayrob.

Didn't it start flickering at near 1.5A?

Default Re: Drivers for 445

I did not test with a diode...

I tested with a red test load. The driver was good with the red test load.

But the test was just a few seconds.

I will be putting a flat piece of aluminum the same size as the driver on the 5 pin chip to heatsink the driver per drlava's documentation:

http://www.sonic.net/~jayrob/V5 FlexDrive.pdf

I will just use some thermal adhesive...
