LM5123EVM-BST: PCB information

Hello Mark, 

Thanks for reaching out. Let me make sure I understood the question, would you like to know the copper thickness (oz) of the EVM PCB? If yes, let me check this and come back to you. 

Kind regards,
EM

Hi EM,

you are correct, customer would to know this information.

Mark

Hi EM,

one more question, 

because customer would like to evaluate PCB layer and copper thickness for 300W output.  the design spec as below:

Vin=9V to 16V

Vout=32V.

Pout =300W.

if they use 4 layers of PCB, only top and bottom use 2oz, and use 1oz for inner layer. do you have any concern on that?

Regards,

Mark

Hi Mark, 

What would be the reason to have layers with different thicknesses? Usually, I've most often seen boards with the same amount of copper. 

Kind regards,
EM
