Automotive electronics，want to be compatible with 12V Battery or 24V Battery input, any power ic recommend? Thanks!

Hui,
You will need be a lot more specific about your requirements. What is your output voltage and current? Do you have cold cranking, load dump and transient requirements on your input? Any other features such operation out of AM band? Let us know.

Hui,
