SMPSU5V

Me likey! :)

just built a +15v/0/-15v "modular" psu for the VCF with 7815/7915 "center tapped" linear vreg standard approach, which still may be of interest to you, because unless you build a modular monster, the current draw for a few modules is not so high, that using linear regulation would burn excessive heat...

But this switcher then is great to efficiently get 5v from one 18VAC transformer coil, without burning so much heat! :)

Hi hawk. First I thought this was gonna serve as psu for non musical stuff - like the mb64e-ish box Im building.

Then I decided to try it in my SID synths too. - for 5v rail. I still gonna use linear standard approach on 9 / 12v rails for SIDs. - so sure Im interested in that! ;)

For the stereo SID synth - the one that is getting the funky spaceship case - Im gonna need +5v, and +/-9v, for 8580s and a balanced transformer output. thought I would just get away with using 9v, on both the SIDs and the audio circuits to reduce the number of vregs in there. Can then use a 12v centertapped transformer on everything if the switcher design works out well :D.

Nice work Techno.

Reminds me i should really finish my smps psu design for mb6582 :whistle:

Nice and efficient! :D
