Hello TI

I need to build buck-Boos converter based on LM5176 and I'm using LM5176EVM(evaluation board) as a reference my questions listed below:

1. does the evaluation board copper thickness is 1Oz?

2. is it a must to use 6 layer or could I do layout using 4 layer PCB?

3. there are some differences between Evaluation board BOM and what recommended in LM5176 calculator such as the inductor ratings.

Hi Anas，

Thank you for your patience. Since the engineer who response this device is still on vacation, I will try to answer what I know.

#1, 2Oz.

#2,The number of layers mainly depends on the specification requirements of your design, as long as it can meet your application.

#3,The document provides a reference calculation result, more often we need to make adjustments based on actual conditions, such as requirements for efficiency, ripple, etc.

Hi Anas,

I have not seen an update on this thread for the last 13 days.
Maybe you could solve this issue already in the meantime, in this case it would be great to press the is solved button.
If there is still something open, just let me know with the new details.
