Hi,

I'm going to be running a 48V (at 3W) boost converter and a 5V (at 5W) buck
converter off of a 12 V battery.

Is it a good practice to have a fuse on both supplies' inputs or just 1 for
the system?

>From a bit of research my understanding is that I should use a slow blow
fuse to handle the inrush current into the converters and I should size the
fuse at 150% the nominal rate.  Is that in the right ball park?
