Hello.

LMR14050SEVM is implemented on 4-layers PCB.

Is it possible to use a 2-layer PCB-layout for LMR14050?

yes, you can, only you need take care the thermal due to 5A current. and the EMI performance is worse then 4 layer board.

Thanks

Hi Slava,

Pls simulate your application in Webench to check if thermal performance meet your requirement.

Hi Andy,

could you please point me, where in webench can I define the 2-layer PCB requirement to simulate a design?

Thank you.

Hi Slava,

Sorry that the latest Webench on TI.com has no option to change PCB layers.

You may go ahead with 2 layer PCB and refer to EVM layout design, if thermal performance can meet your application requirement, then you may have to use 4 layer PCB.
