I really want to use this DC-DC converter (I cannot find any comparable ones,5v 3A, for such a price) for a project but I may be receiving voltages up to 14.5v and it's limit is 13.8. Can I use a diode or something to drop the voltage by 1v? Or even 2v would be better. According to it's efficiency chart I don't suspect the input will ever sink more than 2A. I am also not worried about the voltage being too low, I'm only getting 5v out of it and with that voltage drop I still shouldn't ever go below 11-12v. There's lots of different kinds of diodes and I really only know much about zeners, which would be best for this, or should I do something completely different?
Calculating its power dissipation would simply be voltage drop*max amperage, correct? What if I also used a 13v or 13.4v zener to protect the input, how would I calculate what it would dissipate? How many amps would be flowing through it if it was sinking extra voltage to ground?
Thanks
