Hi everyone,
I am getting back into the hobby again.
My main question is the title really - the diode i plan to operate is a 405nm 150mw diode(a SLD3236VF). The forward voltage ranges from 5v to 5.3v max - with a driving current of 140-150ma.
I plan to connect a 3.7V 18650 Li-ion battery to a 3v - 5v step up buck converter, then on the 5v output I plan to stick a 1W 36 ohm resistor along with the laser diode - to maintain a ~140ma current at 5v DC.
Will this be sufficient to operate my diode in a diode safe manner at/close to its rated output?
Or am I much better off using a laser driver board?
Thanks everyone!
