# USBC Synth PSU
* uses STUSB4500 to negotiate 12v or 15v from a USBC power bank
* uses 4 [DC/DC switchers](https://www.ti.com/product/TPS56339) to supply 12, 9, 5 and 3v outputs for my various synths
* resistors can be changed to set different output voltage
* JP1 can be bridged and 12v DC/DC components not placed if power bank can supply 12v.

# Project log
For build notes, problems and fixes, please check the [project log](docs/log.md)
# Errata
* hole size is 5.3mm, should be 6 for M5 - fixed in PCB, not in gerbers
# Future improvements
* make the switcher parts snap-offable
