Well, I'm planning to use Mini Automotive Blade Fuse. Is it ok or HRC fuses must be used?
I have some hands on experience in that area.It's pretty subjective ...
Only skim read this thread, but is there any reason why a buck/boost regulator could not feed a decent pass transistor for the current?
Simply.... there's no reliable and cheap buck converter which can handle 8 amp job!
Post #11 clearly contradicts this. Maybe @PerryBebbington can provide some links. I'm also curious about this.
I really don't see the need, I typed buck boost converter 10A into Amazon and got loads of them, some under £10. No idea if they are reliable...As you seem unable to do this here's an example, there are loads more buck boost 10A
I personally think automotive blade fuses are horrible things, but they seem to do their job so maybe I am just expressing a personal preference.
