Part Number: LM5155

Hi Team,

My customer want to find a Boost, which is 12Vin and 36Vout and output power should be 300W.

Customer want to find a interleave control boost.

LM5155 is suitable but the output power is not big enough. Could you kindly help to check whether we have more suitable solution for such a high power?

Hello Amelie,

Thanks for reaching out. I will check if we have reference designs available for this output power and come back to you as soon as possible. Just for my information, would your customer consider as well a 4-switch buck-boost that fulfills these specs or a synchronous boost?

Kind regards,

Elisabetta

Yes, all the solutions are welcome. The only request is 300W output.

Hello Amelie,

I would then suggest a synchronous boost with a dual phase approach. At this page you can see some reference designs made with the LM5122 your desired output power https://www.ti.com/reference-designs/index.html#search?keyword=LM5122

Kind regards,
