Mah first sticky, yay
What do you need it to do?I noticed that you said a flexdrive is the best driver right now but from what i have been reading elsewhere that flexdrives are near impossible to get now. Is there a new buck boost driver you would recomend now that the flexdrives are out of the question?
At the higher currents required for high-powered diodes, is not really the IC's voltage drop that matters. If you power a diode with a 4.75 Vf at 2.3 A with any linear driver that is fed by two cells, the IC will basically drop the same voltage (the difference between 7.4V nominal cell voltage and the diode Vf + reference voltage of the IC).New to lasers, so sorry if this has been addressed elsewhere...
Is there any reason I don't see the LT3080 or LT3083 mentioned here for linear regulation? They are voltage regulators like the LM317, but their feedback mechanism works differently so you can make them work as current regulators more easily (and with substantially less voltage drop).
