New 4 Channel Highside driver

[Badpip]

Thomas,
Your driver is the easiest to use. Very Stable output. EXCELLENT DESIGN!
Thanks,
Steve

Thank you for the nice words - I'm glad you like it

Hi
Im interested in one, but have a question. I there a way to run different diodes that need different voltages with this driver? Like using the 445nm diodes and the lpc-826. Thanks, Im new with working with diodes.

yes that is possible. Shoot badpip a PM , i know he has several in stock. If he doesn,t reply within a few days from now shoot me a PM. I have a couple also.

These things are great, I got several units and have now put a few into use and they work great

Sure, nothing to worry about there - LDs are current controlled, not voltage controlled, so the driver will take care of that for you

Thomas I have been playing with your driver a bit, looking great so far!

Had a question, is this driver only meant for diodes that run on 5v? Is there a way to have it output 3v like the lpc826? I may be missing something but it looks like the pots on the board adjust current but not voltage. Do I need to use a DC/DC converter to run a 3v diode?

Thanks!
Mike

Just received four of these in the mail. Won't have a chance to play with them for about a week.

Laser diodes are current controlled devices (not voltage controlled). The important thing is to set the 2 pots for your 0v and 5v modulation signal i.e. when your modulation signal is 0v set the bias to just below threshold current of the diode and when at 5v set the gain to the max current you wish to run the diode. Don't worry about voltage of the diode.

Hi Mike, as taggalucci writes, you don't need to worry about the voltage - the driver will take care of this for you

Sounds too good to be true.

It is ok to use the diode with this board to to determine the threshold current? I was wondering if it would hurt to turn the bias is low, then connect the diode, and then slowly turn the bias up until the diode lights up? Or is there a better way to determine current threshold?

Thanks,
Mike
