Other Parts Discussed in Thread: LM34936, LM25118, LM34936-Q1
Hi team,
Could you advise me if we have suitable solution for below requirement?
Vin=3V-18V, Vo=13V, Iout=28A with AEC-Q100
Is LM25118-Q1 or suitable?
Thanks.
Regards,
Allen

Hi Allen,
Thank you for reaching out. The power is 28A x 13V = 364W. Even if it is 100% efficiency, you will need to draw 121A current when Vin drops to 3V, sounds excessive for any single converter.
The LM25118 cannot efficiently support 364W. You need a converter using the sync FETs like the LM34936-Q1. You should consider 2x LM34936, and use the simple current balancing scheme presented in the following article.
