Schematic Review of Clock Project
« on: June 20, 2020, 09:04:13 pm »
Hi all!

I'm new here, and I believe this is the right place. I have a design I'm working on, and was hoping someone could give the power and USB portion of it a look over.

The schematic PDF is here: https://drive.google.com/file/d/1Uuv5jio_vhPbxPwsWwzzxBKSSQ_cVjdH/view?usp=sharing

Synopsis:

I'm trying to power a 132 LED ( of which, 60 are RGB) clock via the Type-C port. I want to take advantage of the USB-PD spec, which is why I have the STUSB4500 chip. The plan is for normal operations it gets 15-20V, passes it to a DC/DC converter, and then get 5V over 2 seperate rails.

There's also the microC logic, which sits between two bidirectional power switches. The idea here is if the board is plugged into the PC, I would be able to program the microcontroller. 
I don't have much experience with BPS's, DC/DC converters or the type-c, actually. I was hoping you guys could help me out and look over the power portion of it. The schematic is 11 pages (8.5x11), but half of those are just LED's.

I'm sure there's some really dumb dumb small brain mistakes on here |O |O, hoping to learn at the very least.

Thanks!
