Hey All,
The
"SXB-2 V8"
So the SXB is final here.:wave:
"SXB" Stand for !!!.Super X-Boost.!!!
I know alot of you have been waiting to be able to use this driver to drive your 9mm diodes off 1 cell Above 2A down to the proper 3.6v or less for some time now...
Most remember the Original SXB thread here:
http://laserpointerforums.com/f67/sxb-laser-driver-2-1a-boost-78974.html
The original SXB had its limitation that i was not happy with. Mainly heat at higher currants. Was not able to control it at 2.4A output. So i was not happy with those becoming available for you guys at the time. So i went for the larger brother package.
So then came this Version.....
The "SXB-2 V8"
The design and though behind this driver was simply 9mm 445nm diodes all the way.
People are running them as high as 2.6A.!
So we needed something capable of that or Above and the SXB Solves that.
With the drivers available now including my X-Boost there are limitation to them.... I wont get into to many details but Mainly the switch on the drivers are not high enough to properly boost anything above 2A down to 3.6V without maxing out the switch or very close to it. Again to be clear Iam not saying they cant but saying they are very close to maxing out at 2A or higher etc especially when the cell starts to drop voltage.
I did alot of thinking on this driver. I made the driver 26mm round and a flat bottom with some exposed copper to be mounted flat to a heatsink. Now i dint have much control over the size of the board but really 26mm is dead perfect for such a monster driver...
Anyone that is running at 2.4A with any boost drive will need a beefy host and in that case pretty much all beefy hosts can fit this driver. I was going for the best performance not size.!
However with that said i will be making another version that is either a 2 sided board or a dual board setup so that i can make the driver smaller for the crazy ones that want to use it in a Thinner host.:na: However dont expect to see that too soon.
I made 2 Holes on the board so you can run your wires out them for your voltage input.
I recommend you use 22AWG wire at least for the driver. Especially at the Higher Currant.
Good quality cells are also a must.!
The Driver is Pot Adj and has 2 selectable ranges. A simple Bridge across the 2 resistors and thats it.
There is Also a Fixed Version for those that dont want to deal with the Pot.
The Driver is Continuous GND as well. Thanks to the Zentex Op amp that RHD said to try out some time ago. I have a diffrent op amp that i have been playing with so future version will have a diffrent Op amp. THough not much diffrent in performance just i prefer it.
So about 6 months later i give you the final look at the SXB-2 V8.
Spec's:
Name: SXB-2 V8
Kind: Boost ONLY
Input Voltage: 2.8V-6V
Output Currant: >3A (~ 4.5A MAX on a 5V load)
Version: Pot ADJ or Fixed
Over heat protection: ON
Soft Start: ON
Sensing: High Side
GND Line: Is Continuous
Size: 26mm Round "Flat Bottom"
Price: $25-$29
Here are a few pictures and a video i shot several weeks back.

Here is the video i made a few weeks back. I will make a new video in the next few days since the one i show in the video was the version that had the dual board. There is no difference in performance or anything. But ill still make the new video since i have me new Testload as well and everything will be easier to see.
Hope you guys like it.:wave:
:thanks: For Looking.!!!
