Hi Cliff,

Do you need isolation between input and output?

Dear Andy

The design is still under evaluation now.

Can you provide suggestions separately (isolation and non-isolation )?

Thanks

Hi Cliff,

LM5122 Boost controller is suggested for input --18Vdc ~ -76Vdc to non-isolated Output 12Vdc, then use low voltage buck converter for 5Vout, please check it on E2E for LM5122 application support.

LM25037 is suggested for isolated conversion
