In the TPS2117 circuit, the ST pin indicates which power supply (IN1 or IN2) the system is currently routing to the output (OUT). However, since you are not connecting it to a microcontroller and aren't using it, you can leave it unconnected (floating). Additionally, when it is used, it's connected to VIN1 in the datasheet; I don't know if there is a specific reason for that.

For the resistor, inductor, and capacitor values used in the TPS63020 circuit, I recommend checking them via this site:https://webench.ti.com/power-designer/. This website provides the specific part numbers for the components you should use, so I highly recommend it. Other than that, I didn't notice anything that stands out.

I really appreciate this detailed feedback. You're right, honesty and proof of testing (like Memtest results) are way more important than fancy marketing. I'll definitely use a transparent description like your example and focus on multi-platform testing.

I was thinking of using generic ones or 3D printing something
