WEBENCH® Tools/LM5122-Q1: PCB for the following configuration has overlapping footprint for the capacitors: Input: DC 38 V - 57, V Output: 60 V at 31 A

Hi Nishil,

Thanks for your interest in LM5122. Could you resend the picture? I cannot see it here.

Thanks,

Yinsong

I have attached the PDF, schematic and PCB file as well.2020-09-22_10-22-55.rar

Hi Nishil,

we will take a look and we will get back to you by next Tuesday.

Thanks,

Hi Nishil,

Thank you for the files.

Could you explain more about what you are trying to do? Is your PCB size limited?

Thanks,

Yinsong

Hello Yinsong,

No, the PCB size is not limited. I want to develop a boost converter for DC 38 V - 57, V Output: 60 V at 31 A.

For this, I was using Webench tool but as you can see the footprint of capacitors is overlapping. There should be 20 capacitors according to the schematic, but if you check the PCB, you can see footprint of only 5 capacitors and rest are overlapping over COUT1.
