Setting current on driver from voltage. Transfer function. Check me?

Hey guys.


This should actually be an easy one.


Im playing with a PLD 5000 laser driver. Adding a diode to my cnc machine. It has a current monitor pin, as in you can read the outputgoing


Anyways, it says, in order to set the current from a voltage reading, use the transfer function:


V=I(LD) /2A/V




My driving voltage is 12V. I'd l ike to hit around 1.5A

Am i correct in guessing that 2(1.5)/12 = 0.25=V?


Ie that if i read V=0.25 on my monitor pins, Im at 1.5Amps on the output?

Thanks in advance!

This means

Diode current = 2 Amps per Volt measured at monitor output.

So if you read U =0.25V, then this means 0.5A through the diode.
