Hi folks!
Currently I'm working on a simple laser engraver. Therefore I have used
one of these 3W Diodes from DTR.
The recommended current is 2.4A.
Now I must be able to switch the diode constantly on/off to engrave structures.
The maximum frequency will be ~1kHz at the really tiny structures.
But as far as I know its much better to reduce the current flow through the diode to a minimum instead of turning
the whole driver off and on again as this will prevent voltage spikes and such things. That way my diode will live longer :yh:
Because it will be a tiny engraver the dimensions of the driver should not exceed 30x30mm (~ 1.2x1.2 inch)
So does anybody know where I can buy such a driver capable of at least 2.4A?
Even better for me would be a circuit which I can solder myself so I dont have to mess around with driver dimensions.
To sum up the features the driver must have:
Thanks in advance!
:thanks:

To sum up the features the driver must have:
- > 2.4A current
- Adjustable output voltage (or enough for that specific blue diode)
- Digital modulation (TTL / PWM / whatever)
- Tiny enough / circuit that I can build myself
Thanks in advance!

That is the recommended handheld drive current, if you run it at that current for longer times (i.e. in a laser cutter) then you're going to see a significant drop in power after a while.
