Preparing for the future, drivers!

[dave]

Just finishing a new driver with a dcdc converter on each channel. Can be powered off up up to 30v making it able to run off the scanner psi :-) also have a microprocessor based tec driver pretty much done :-D exciting times ahead!

[Bbe]

To begin, I plan to release a single-channel version.
It will be inside:

Board size - 30x50mm, fully surface mount
Input voltage up to 28V
Output voltage - regulated
Output current - up to 3A, highside
Start delay + slow start
Board overheat protection, laser diode overheat protection
Interlock In/Out, multifunction status LED

There is no problem to combine multiple channels on one board
Also I have tested prototypes for 6 and 9A versions

...ha ha, I forgot about the b.... Of course, beam suppression (with a delay) and fine "zero" adjustment is available in this driver
+ standard protective measures: overmodulation clipping, PSU overvoltage, wrong polarity...

Bbe,
Is this an alpha or beta version, or have the units been tested in the field "real-world" environment for a while, say a year or two? If so, what are the return (RMA) qty numbers ? Have they been HALT/HASA tested? Not trying to be nosey, just would like a little life-test documentation. Thanks.

[Bbe]

Steve, this design is tested by me in previous versions of the driver, which I used in my modules. To be precise this is RC version. I did the standard tests only. Overcurrent, overheating, incorrect polarity, etc...

Board size - 3x5mm, fully surface mount

A tad small that is

oops
updated

Sorry to pry some more, but it's my job .. How many revisions has this board had? How many engineers and technicians were involved in the research and development of this board and it's circuitry? Sorry, but before we all start putting this board in our projectors I'd (We'd) just like to know that it's time-driven trustworthy, and not just a "flash-in-the-pan" .. we've had so many of those as of late in the last few years. I hope you understand .. Thanks .

I agree; there are loads but Bbe seams to be on the right specification tracks; now if only he/she would fill out his location so we know this is a trust able source. Then we can consider it.

I understand you, Steve
This board had 2 revisions in the design stage. 1 engineer was involved

This is one of the reasons why I started designing the driver. I have not seen anything on the market suitable for me and for professional use

Andy, you are bound to remember me

I have a DIY driver board with 3 channel modulable constant current source for RGB (for green up to 10A for R/B up to 2A)and 3 channel simplified PID controllers for the TECs.
Key switch for the diodes (interlock ?)
delayed power on(10-30secs variable)
bias gain up to 10%
onboard status LEDs and output port for outer LEDs(RGB and working status + ilda recieving status LED buffered from the X/Y signals)
It doesn't contains the beam suppression circuit.
Powered by 12V+5V (ATX PC power supply)
It is looking awful and not too tiny but that is mine and works proper.
I do not sell anything and won't make PCBs or laser driver for anyone :P
Here is some picture of the complete hand made PCB hahaha

I dont know why did i posted this...
Merry Christmas Happy holydays and NY!
