I've been tasked with designing a circuit (actually a buck/boost converter outputting 20 Volts at up to 10 Amps) which takes "automotive voltage". This product will be subject to some sort of official automotive certification. Nobody at my company is currently able to tell me exactly what that means. We're going for cost, and it needs to be integrated into our PCB, so yes I'm looking at using certain TI chips, discretes, etc. Like a normal dc/dc supply, not a module to purchase.
Can someone give me the brief summary on what "automotive voltage" looks like? I've been told it can go as low as 6 volts, but nothing so far in terms of spikey transients, picking up noise from other junk under the hood, etc.
In other words, what filthy input must my circuit deal with?
I'm sure I'll get a real spec eventually, but for now I'm putting together a block diagram so I'd like to get an idea of where to put in the various filters, emi junk, voltage protection, surge suppressors, etc.
Is there a 1-page AEC summary or something?
