Neither webench or power quick search return any results for those inputs. Let me see if we have any close reference designs.

Hi
2-phase LM5122 might be able to support your requirement.

Yes, LM5122 is what I suggest also. There is a reference design for a similar application.

Thanks for your reply, but LM5122 just can be used in boost circuit. i want get a SEPIC circuit for automotive Start-Stop system. if you have LM5122 SEPIC reference design that can support my requirement, please provide.

And i want to konw if i use LM5175, can it support my requirement? Do you have some LM5175 reference design for a similar application.

thanks and best regards

There is an audio reference design for LM5122. I did not look at it to determine the topology used. It was the only design that filtered to your basic requirement. I can check it later.
