I'm looking for a way to protect a small circuit which is to be used inside of a car or truck (12V or 24V power system). The circuit consumes about 12-15W. I use an isolated DC/DC converter module which can regulate 9-36V down to 3.3V.

I'm looking for recommended circuits or a controller IC that can take care of the usual hazards:

1. Load Dump Spikes
2. Reverse Voltage
3. OV/UV Protection
4. General noise on the power lines.
5. ... Anything I might have missed.

Currently I have my eye on the [LTC4365](http://cds.linear.com/docs/en/datasheet/4365fa.pdf) from Linear Technologies. I've thought about using it together with a bi-directional TVS, clamping the voltage to 32V and protecting everything with a fast blowing fuse.

Would this be a proper solution or did I miss something here?
