I think maybe I understand the driver example in the SPL PL90 datasheet a little better now.
I couldn't fathom all the inductance coils, especially as it states "it is very important to minimize the inductance of the circuit."
Perhaps L1-L5 are there to remind the engineer that inductance is...
Where does the high voltage go?
Would it be too heinous a simplification to say that:
As the laser diode attempts to draw an infinite amount of current the voltage increases, but the capacitor is emptied before current (and voltage) can exceed specified limits?
Or is that just total...
Sorry, for bumping an old thread, but I think this will be of help to future readers, and it's an excellent resource thanks to keith.
$150 is not unreasonable if you only need 1, but if your project requires multiple drivers, then it gets a bit expensive.
Here is a design from **broken link...
