For the Meanwell RPT-60B (sitting nicely on my desk now, thanks NorthernLightX!), some extra electronics are needed to provide me with additional smooting (which is mainly a precaution, as the power supply itself seems to have a lot of smoothing capacitors already), but more importantly needs to convert +12V into +9V for the 8580 Sids.
This is the schematic I've come up with so far:
I'm not sure if I implemented the latchup protection right, as I still don't really understand what's going on (I just copied from what was posted earlier).
I will be using the modular SID boards, which will be connected to +5/AGND and +9 (which has no AGND to prevent ground loops on the SID-board). Now, if I understand correctly, to prevent latchup directly before the SID-chip, a diode needs to be placed between +9V and the AGND connected to the SID (coming from the +5/AGND rail). Also, I saw Shuriken used 1N4004 diodes in his schematic, but wouldn't a 1N4001 be sufficient as well (as 50V is quite a lot)? And could I maybe also use the 1N4148 here, or are those too small?
Also, I'm thinking of using a metal film and a ceramic 0.1uF capacitor on each rail, as they both provide different smoothing caracteristics (so I figured they will complement eachother). And when using this schematic, is there any advice on the smoothing capacitors on the SID boards? I intend to leave the whole regulating circuit out on the SID-board (rectifier, capacitors, regulator, capacitors), but I'm thinking, would it help protect the SID in any way to leave the (last) 0.1uF capacitor on the 9V input of the SID?
All thoughts are appreciated! :)
