RVL-PSU

The RVL-PSU is a custom regulator solution for your portable and non-portable projects. It provides system regulators: 1V, 1.15V, 3.3V, and 5V. RVL-PSU does not provide any battery management. For projects involving batteries, it is recommended to use the RVL-PMS instead.
Improvements made from the previous version:​
  • Screw holes on the corner of the PCB for mounting in your enclosure
  • Optimized components and PCB layout
  • Solder pad jumper for setting power to the 5V regulator if it is not required for your application

Specifications:​
  • Vin (Min): 5V
  • Vin (Max): 17V

I have created a revised BOM, as the current one does not contain any Ref Des's, a lot of the passive components are out of stock, the quantities for components do not match the quantity actually used on the board (set for best unit cost), and contains a couple components that aren't even used on the board. In the new BOM, all of this is fixed, just plug it into Digikey and go.

With that being said, there is the issue that the TI buck regs and the inductors used on this board are out of stock on both Digikey and Mouser. I bought some aliexpress knockoff chips and inductors, and assembled my boards using them. After wiring one of my boards up to a 6-layer, I can confirm that the ICs and inductors fit the bill and work as they should (at least for now).

Here are the exact listings I got my ICs and inductors:

Hello friend, I want to make my board for my wii but I don't know how to place the components correctly, you have an image of your board or a guide on how to place the components correctly.

All of the Reference Designators (Ref Des's) in the BOM (that I updated in my previous post) match to where the components go on the board (little white text next to all the components). If you're wondering how to orient the ICs, see the little white dot at the top left of the IC footprints. That should match with the marking on the IC itself. All other components on this board are non-polar, meaning that their orientation does not matter.
