Following your advice on "

LM3488: LM3488 What is the difference with LM3478?"

I looked into the LM5155 and put my requirements into Webench (11-15V in, 15V out, 15A) and it didn't even suggest the LM5155.

I looked into one of its suggestions using the LM3478, and it recomended a Vishay diode which is now obsolete.

Hi Ian,

Thanks for your interest in LM3488 and LM5155.

The problem here is that the load is too high. Please consider using a synchronous controller like LM5122.

Thanks,

Yinsong
