I've recently started on a 1W 808nm project. I have my 9mm diodes and the person I bought them from says they can be driven up to 1000mA, I tried using a DDL circuit I had laying around but it will only go up to 480mA with the .5ohm resistor and 100ohm pot turned to the highest mA. Ive tried wiring it up a couple different ways, it worked once and it went up to about 2amps, but then it didn't work once i got it soldered together onto a board.
I was wondering, rather than using 1 driver to power 2 diodes like other threads that have come up in my search, but using 2 drivers to power 1 diode? Ive tried wiring it up a couple different ways, it worked once and it went up to about 2amps, but then it didn't work once I got it soldered together onto a board. I'm sure they can be put in parallel but I'm not sure how to hook it up (drawings appreciated)
