Hi,

I need to design an power supply Vin=35~70V Vout=13.8V Iout=15A

I find LM516-Q1 has an EVM design LM5146-Q1-EVM12V of 12V/8A as the link

And can you tell me whether LM5146-Q1 can fit for my requirement?

Hi ,

This EVM Imax=8A. Your needed spec is 15A. You should change your overcurrent protection and layout.

Thanks,

I know I must change the overcurrent protection and layout to fit for my requirement.

And I want to check that whether LM5146-Q1 can be design for requirement, because my requirement is up to 180W.

LM5146-Q1 is OK for your requirement. It is a controller.

Please use the LM5146-Q1 quickstart calculator to assist with component selection and to view efficiency and loop stability plots. The file can be downloaded from the product folder (under Design and Development).
