I have drlavas spec sheets for the groove 2, micro flex V5, and micro boost V1 drivers on PDF, should I upload them here?

I also have the PDF for the rckstr micro driver V3...

EDIT: Here is the Groove2 and rckstr V3 PDFs

What about linear amc7135? These are great for the inexpensive red diodes. I have one of these driving an LOC at ~350mA.

amc7135 is a ground-side regulator, and will only let 350mA pass through. Paralleled, you can let multiples of 350mA through.

inexpensive and easy to find, too.

testing still needs to be done on the cleanliness of the 'output, but it's a viable option?

Okay, enough information to start organizing. Could someone please point out how they fit based on lasersbee's criteria? (Sorry but I can't read each and every one of the links, got an exam tomorrow :().

http://laserpointerforums.com/membe...-p/3041-lt3080-working-2-some-more-current-p/

Just a pair of linear drivers, very low dropout, current feedback.

More to come :p :D


EDIT: is just my impression, or all the die4drive, stanham, flexdrive, and so on, are basically derived all from the old "op-amp / mosfet" current sink configuration ? ..... asking just cause, basically, they look similar to the one i use for labbies, took from a datasheet years ago .....

How's about these drivers?




:crackup::crackup::crackup:

Sorry, I had to....
Uhm ..... the first one does not fit nor in an aixiz module, nor in a labby cabinet (and it's expensive, cause require food also if you don't use the laser) ..... and the second one, can be fitted in a labby setup, but require too much muscular efforts for work good .....

:eg: :crackup: :crackup: :crackup:

There are also other DIY drivers - LM3410-based drivers such as Eudaimonium's Spark driver, and op-amp based current sources. The LM3410 can be run as a buck, boost, or buck-boost converter depending on how it's wired. The op-amp based design would be closest to a linear driver but as HIMNL9 said, probably deserves its own category.

This is my first post to this forum after a fairly thorough lurking period.
I have 2 nagging questions so far.
Am I missing something or are you guys??
Why is there what seems to be a conspicuous absense of driver circuits based on the TPS63000-Q1 minimal component, high quality, high efficiency, buck boost converter??

thanks for the guidelines and feedback.
I have been unsuccessful acquiring samples.
the first person who prototypes this will become the new expert on it.

addendum..
description: advanced, high efficiency, single inductor, buck-boost converter chip
brand: not prototyped yet
version: n/a
type: buck/boost converter 10 pin qfn powerpad package
voltage input range: 1.8-5.5dc
startup input voltage range: 1.9-5.5dc
output voltage: 1.2-5.5 adjustable
current ranges: up to 1.2amps out at 3.3v buck mode with Vin= 3.6-5.5vdc
up to 800 ma out at 3.3v boost mode with Vin > 2.4 vdc
switching current limit: 1.6-2.1 amps, 1.8 amps typ
other features: up to 96% efficiency, power save mode available, thermal shutdown protection, minimum addon components, soft start, small package size
notes: advanced design will need specialized heatsink and soldering methods
approx price (chip only): $2.35 usd for 1000 unit quantity
pdf sheet containing circuit, parts list, and full parameters:
http://focus.ti.com/lit/ds/symlink/tps63000-q1.pdf

and yes, drlava, i did lurk my way thru the flexdrives etal.

just a thought.. only post on the driver that you have. in a neat format. that way niko can add it all later easily. don't post ..."what about a lm317. i will start

brand: rkcstr
volt input: max 12
volt inpun min: 2.5 just for driver + need voltage for diode
current range upto: 440
fits in aixiz (just barely)
price: 13usd

brand: lava
version: v5
type: buck/boost
votage input range: 3.5-5.5dc
current range: up to 1amp
fits in aixiz
price: 23usd

brand: "ddl"
liner driver
voltage input up to 20vdc + voltage needed for diode
current range: up to 2amps
Type: home made
does not fit in aixiz (good for project box type of set up)
price: up to 10 usd

I'll edit again shortly after doing some more research.
Please see: FlexDrive V4 through V5 :)
