Oclaro/USHIO 120mW Single Mode 638 Diodes (HL63603TG)

[Blord]

Looking good. Thanks for sharing the information. The diode have a maximum output of almost twice the nominal power. Just like the PL520 diode.

Crap. I destroyed another microboost. Well, it may me repairable, but not for me. I hate SMD. I love caffiene too much...

I've got more on the way, and will set it to 280mA, just like my PL450. The jumper setting to get 300mA has become a nice way for me to destroy these drivers.

So I hope to have another single mode ready by early next week.

Microboost?? You don't want to use one of those with this diode.

 

[IsaacT]

Why do you want to use with this diode?

 

[shokkunlasers]

Microboost?! From what do you wanna boost 1.5V AA battery :na: (I dont even know if they boost from so low voltages:shhh

I think the cheapest and easiest driver would be a single AMC7135 and maybe add a XR7/6 10uf against the current ripple

Do you think 350mA is ok for long life?

 

[Blord]

It is single mode and the beam is much brighter than a 660nm beam. I would say 3x as bright at the same output. It is good to see a round dot instead of the ugly barshaped dot.

 

[ChaosLord]

Yeah, a microboost. I was unsure due to the low voltage drop, but then at higher currents it drops more, so i thought it would be ok. Now im glad i didn't quite make it.

I was going to try a moh linear that i have, but it's set a little high and wouldnt fit inside the module.

Using just one batt isn't a big deal, but i want to use the whole module. The microboost was all i had on hand that would fit. Is there a linear small enough to fit inside the module?

 

[awillis2589]

how much are these diodes running??

 

[Lazerbeak]

Thanks for putting the time into this and sharing DTR! .5a 3.6v 233mw very nice. A burly diode indeed

Biggest rule about boost drivers. Aside from 1 cell (as I have learned the hard way). Don't boost reds.

 

[IsaacT]

So will a linear driver work for this? And if so do we use one Li-Ion?

With a linear, 2x Li-ion will do the trick. Mine is running off of 2x 16340 with a mohgasm linear at 200mA. A single 18650 will work but I only got about 65-70mW.

 

[IsaacT]

Ah okay, that sounds about right. I had similar results with my 650.

 

[bloompyle]

Made an edit to 2x li-ion. Sorry for any confusion. Technically 1 will work, but your best bet would be 2.

 

[awillis2589]

found the price, and I think DTR is trying to put me in the poor farm with the RBG combo!!!

 

[ChaosLord]

Now im glad i killed the driver. Better that than the diode. Thanks guys for the info.

I've got both a linear and an X-drive on the way. The only driver i have currently is a moh linear set to 378mA. It was meant for another 650 build, but got tempted to use with this.

However i will wait, as i don't want to push it quite that hard.
