If you plan to run this in a car you really need a surge clamp on the input. People have been experiencing LCD s fail and its nice to just rule a surge out of the equation.
Almost every single piece of electronics I have ever taken apart have a fuse on the input (or that I've designed at work).
I'm a hardware engineer by day that designs DC/DC converters so if I come off sounding rude I apologize. I don't work in the automotive industry but rather tel com so my surges are lightning induced and a surge clamp is mandatory!
