Hello guys, I'm building PCB that includes a powersupply for the Rapsberry Pi 5.
I made below here a powersupply, can it be improved or designed better for the application?
I use the powersupply in my boat to convert 12/24V to 5V/5A:

If that DC supply also feeds any other loads that may generate a noise signal on the power feed, then I suggest adding some series inductive elements to block the noise.
THAT will include filtering of both the positive and negative input conductors.

In addition, the indiscriminate connection to "Ground" is very likely to be a source of undesired noise signals on the regulated power section of the computer system.
As for fusing, or some form of over-current protection, that should be provided in-line prior to the power feed entering the PC board. Itsould also be prior to the suggested input power filtering portion.

He mister,
This power supply will only be used for the rapsberry Pi 5, for the rest i will make a second powersupply.
Here's my updated schematic with fuse on the VIN-line.

I see a lot of schematics on the internet but mine looks a bit more complex, did I overdo it?
