#PPTC

2023-12-29

After failing to create a #symmetric #powersupply using an OpAmp and BJTs to split 24V by forming a virtual ground, I went the easy route. Two #BoostConverter set to 12V each are connected in series with the center being ground. This way I get symmetric +/-12V. Of course I don't rely on the #battery protection, but rather use a 900mA #PPTC #fuse per rail. Also a switch and some LEDs as indicator. Enough #JST sockets for my upcoming #synth projects.

Schematics of my symmetric power supply. it's just a switch, fuses, and LEDs and two boost converters, done in KiCadplanned perfboard layout using KiCad PCB editorbackside of the finished perfboard. the soldering can be seen. I'm satisfied by how clean it looks.front of the finished perfboard with batteries and boost converters plugged in. the LEDs are lighting, indicating that the switch is turned on
