Default X-Boost V7 Mini & Super Mini (8mmx11.5mm) 1.8A Laser Driver

Hey All,

"The Super Mini"

Comes in at: 8mm x 11.5mm.


Pictures:








I think the dime is to big for an Example so lets use a Focus adapter ring to help you picture how small it really is.




'The Mini'


"X-Boost V7"





Just wanted to show this latest Boost Drive that i made.

Most of you guys have all seen my X-Boost. Its nothing New.


Here is a slightly different version using a Different chip and design in order to get it smaller.

It is pot ADJ and can boost up to 1.8A for 445nm down to 3.6v-3.7v off 1 single driver. No need to dual. As well as run 12x diode, Single Mode Blues etc....

The Pot is a Nice and Beefy. Very forgiven. In other words its easy to set and no need to search for a tiny screw driver.

But there is also another cool thing about this driver. The Pot can also be Removed or not put in place and now the laser Driver becomes Fixed for those that hate pots and would rather have a fixed driver and there is no need for any extra modification. Just as simple as that. "I dont really care for Pots"

The Driver was designed simple for Size. Get it as small as possible.

Right now As you can see below its very small. 10mm x 12mm which puts it 1mm larger then the Flex drive/Micro Boost to give you a prospective. It will be getting even smaller then this just need some more time to play with it but for now iam pretty happy with it.

It can fit in most of the hosts out there that you would use such a driver for and fit in the back half of an Aixiz Module.


Here is a quick list of the Spec's.....


Spec's:


Name: Mini X-Boost VS7
Kind: Boost
Input Voltage: 2.7v-6.5v
Currant Range: 100mA - 1.8A
Currant Setting: Pot Adjustable
Over Heat Protection: On
Size: 10mm x 12mm



Here are a few pictures that i took........






Right now these drivers are hard to make due to the Chip they use. Its very time consuming to do it by hand and very hard to re-flow. You end up doing alot of re-work with these chips.

Unfortunately iam not set up at the moment to sell these right now one by one. I have been talking with a Few that are willing to buy them in bulk. So we see how it goes.

I will be making a video shortly so you can see it in action.

Iam very Proud of this driver and its size.

With a few more tweaks it will be perfect to how imagined it.










For Looking.!!!

Wow awesome!
That's a lot of tech packed into a small package. Definitely will be very popular.

Thank you for your contribution to the LPF community!

Cheers!

Looks awesome! Great job on the size too, I think you have the smallest driver that can do 1.8A

Those DFNs really suck. I would go crazy if I tried to make a large batch of drivers with those chips.

Thanks Buddy.

Oh tell me about it. I hate them. They never re flow right in the over and hot air seems to be the best and only way because you can move them around. Even then by the time you do 1 driver alot of time has passed. Must think of a faster method.

Iam already crazy. These have made me go NUTS.!. j/k

After using your X-Drive Buck drivers, I have a really good feeling that these X-
Boost drivers will be very stable drivers as well!

Great range of adjustment, nice small size, awesome!

Can't wait to try some out!

Wowee, this looks splendid!

EDIT: Does it have reverse polarity protection? And is the negative terminal continuous?

Perhaps try a batch on a hotplate?
Reflow the DFNs on the hotplate & do the other side in a toaster. Epoxy the little monster if it tends to move during 2nd reflow.

Default Re: X-Boost V7 Mini (10mmx12mm) 1.8A Laser Driver

Hey Thanks Guys. Glad you Like it.

AnthoT@ You and those damn pots. Thank God i have the option to take it off since i hate them.

Spyderz20x6@ No it does not have reverse polarity. It takes up more space and i was going for size with this then every feature.

It is not continuous GND. Why would It need to be.? What diode would you use this driver with that would need continuous ground. The only diodes that needs a continuous GND driver are 660nm diodes that use there Case pin. I have not come across any other diode that would need a boost drive that is continuous GND. If you need continuous ground you most likely would be looking for a Buck/Boost driver since you would most likely be bucking the voltage down for a Red diode.

HaloBlu@ Not sure if you understand what the common issue is with these kind of chips when re flowing them. The problem is not that they Move out of place,that rarely happens. The problem is with these chips is you get alot of Bridges under the chip where you cant see. You must get the solder just right and even if you do your never sure. Most of the time its between the center heatsink GND pad and one of the Pins. Iam waiting for some New Board to come in which i tried something new for the center pad that might work and help.

Ive got pretty damn good at these chips but i want to be able to do more at once then 1 chip at a time.


Cif@

laserluke@ Thanks Luke.


skyray@ I have no price in mind yet But the should be No more then $15-$20



As another Note I just tried the other night and you can dual these up. I was pretty happy to find this out. I was about to test up to 2.4A down to 3.5v before my 5A supply could not supply anymore power. It really cuts off at ~4.6A. Iam think these can be dueled up way higher then this down to 3.6v. But iam going to need to find a 10A supply to test that.






Here is a couple pictures of my round Personal X-Boost V7 Original that are rated up to 2.5A. IC Max is 3A.

This is my 21mm board size. I also have them in 15mm,16.8mm,17mm,20mm,32mm and so on......

This is the Original X-Boost which is More powerful then the Mini and is what goes in my laser builds i sell.

It is not continuous GND. Why would It need to be.? What diode would you use this driver with that would need continuous ground. The only diodes that needs a continuous GND driver are 660nm diodes that use there Case pin. I have not come across any other diode that would need a boost drive that is continuous GND. If you need continuous ground you most likely would be looking for a Buck/Boost driver since you would most likely be bucking the voltage down for a Red diode.

HaloBlu@ Not sure if you understand what the common issue is with these kind of chips when re flowing them. The problem is not that they Move out of place,that rarely happens. The problem is with these chips is you get alot of Bridges under the chip where you cant see. You must get the solder just right and even if you do your never sure. Most of the time its between the center heatsink GND pad and one of the Pins. Iam waiting for some New Board to come in which i tried something new for the center pad that might work and help.

Ive got pretty damn good at these chips but i want to be able to do more at once then 1 chip at a time.


Cif@

laserluke@ Thanks Luke.


skyray@ I have no price in mind yet But the should be No more then $15-$20



As another Note I just tried the other night and you can dual these up. I was pretty happy to find this out. I was about to test up to 2.4A down to 3.5v before my 5A supply could not supply anymore power. It really cuts off at ~4.6A. Iam think these can be dueled up way higher then this down to 3.6v. But iam going to need to find a 10A supply to test that.






Here is a couple pictures of my round Personal X-Boost V7 Original that are rated up to 2.5A. IC Max is 3A.

This is my 21mm board size. I also have them in 15mm,16.8mm,17mm,20mm,32mm and so on......

This is the Original X-Boost which is More powerful then the Mini and is what goes in my laser builds i sell.





Oh a round version aswell no pot jokes haha just had to
These look great though again

Very nice work. Looks like LPF is giving osh park a workout these days! I wish we could find a good chip that was more hobbyist friendly for a driver though! I know exactly what you mean about the bridges under the chip. No matter how carefully I reflow or hot air some of these chips, I am usually SURPRISED when it DOES work, rather than the other way around.

Plus, if have been doing this yourself, that is,awesome too. I have been working with LeQuack on some drivers and I can't imagine going it alone. It is much easier to figure out mistakes when someone else is looking over your shoulder.

Hey Thanks Man.

When i First started off to flow these and even for a Good time after i was always surprised to see that it worked and dint need to be re worked then the other way around aswell. To this day i still mess up here and there but i have gotten pretty good at it now. Ive re flowed ~50 X-Boost drivers that i use "The 3A ones" which are the same package chips as these are so you would hope by then you would get it right.LOL

What stinks is these chips are not cheap so if you mess up your next board costs double the price to make.

Basically after i got my pattern down it seems to work every time. I just wish i can do more then One at a Time as in re flow more then 1 chip at a time like i do on my buck drive. I can do 50 of those or even 100 at a time if i wanted too and all will flow perfect more or less.

The space between the pin pads is 0.05 on this chip.
The space between the center pad and the pin pads is Nearly the same. if not the same.

I found that Taping the Chip while you still have the hot air on it will clean up any bridges. Kinda Poking the side also helps alot.

I honestly dont even know how machines do it.

I think in order to flow these chips in the oven DIY style you need to have a custom Flux/Solder paste mix.

Believe me i have tried alot of different ways to do it Except getting a Stencil made which i plain too when i get time.

Another you can try is adding Flux on the bottom of the chip spread it around and then dab it off on a napkin so you can see a very thin nearly no flux left on the chip with the naked eye. This helps Quit a Bit actually.


Its always good to have someone to work with. For me i do everything on my own for the most part. However I have had Extensive help over my time in learning in the beginning and even now i still ask for help. There is Nothing wrong with it.

Iam in no way advanced or anything like that. Just alot of trial and Error thats all.

Looking forward to seeing your drivers done.

Ive been so busy i have not been posting much.

Ive got a new version on order now that should be here in a couple weeks. I think you guys are going to like it.

Default Re: X-Boost V7 Mini (10mmx12mm) 1.8A Laser Driver

I have got it down to where I have pretty much 100% accuracy on the no pin chips in the toaster oven. It's been a long time since I've had one short.

The only problem is it takes me 15 minutes to apply the paste for each one!

I have to agree that working with someone on designs is much better. I usually collaborate with RHD on any big projects and it really helps to have someone else double checking your work. We will just email the file back and forth fixing and changing things each time until we are satisfied.

Tom you need to PM me your email so I can send you my designs for the tps63010 when I start working on it.

I really do not know how you can make these Lazeerer. I could never make enough to be able to sell them!

I actually tried that out of frustration and I still got fails.

Oh selling these.? LOL Iam Not sure on that yet. In Large Bulk of 100pcs maybe or if someone Pm's asking for one sure but to sell these like i do the X-Drive i will have to have a little more free time which does not look like i will have any time soon.

But iam going to try.

The TPS63010 is the same chip thats on the Flex drive right.?

If so Dont waste your time other then for Red diodes.

The Flex drive cannot boost higher then 1.25-1.3A for a Stander 445nm M140 4.5v diode as a Single driver down to 3.6/3.7V. Shocked.? I was.

This whole time so many people have been fouled into thinking it can boost to the full 1.6A down to 3.6/3.7V when really its more like 3.9v/4v. I was also one of the ones that was fouled up until most recent last month when i actually tested one.

THe Only way you can get above 1.3A down to 3.6v is if you dual them. Which will give you more switch play room to boost and a second inductor.

Trust me i was supper shocked to see this aswell. But then remembering it only had a 2A switch iam wondering how i dint catch it earlier.

I made a video showing this but dint upload it as its not my place. There is better chips out there Iam pretty sure of it. Plus that chip is tiny.! I can only imagine DIY re flow on that even though its just aligning it..

Default Re: X-Boost V7 Mini (10mmx12mm) 1.8A Laser Driver

That is right. If you only use one 3.7V cell for the 445nm diode the max current of the Flexdrive is 1.3A. You will need more input voltage till 5.5V to get 1.5A out of the driver.
Back in this thread I have noticed this,
Mohrenberg Hotlight 1.3A 445nm
I didn't know better than thinking that I got a dud Flexdriver.
Oh well time has learn a lot for me.

Quote:
I set the driver at the max which is 1350mA. Somehow the driver won't deliver the 1.5A current.
Do you have one for sale ? I need one for my build with 3x14500 batteries in parallel which gives me a working voltage of 3.7-4V max.
