Hi Sir

I want to design a power stage as below, output need 3~25v/5A, Outputs can be connected in parallel

the LM5149 is the right solution for this application?

thanks

Hello Alex,

It possible to use the LM5149 for parallel output. but for 5A it is likely not necessary to use a dual phase interleaved approach. Hope this helps.

Thanks.

David.

Hello Alex,

suggest using single phase only, no need for dual phase interleaved. hope this helps,

David.
