LM5069: Sense Resistor Divider size and Layout

Part Number: LM5069

 We want to use the resistor divider method described in the data sheet for more accurate sense resistor.

The design is going to be able to draw 17A across the sense resistor.  I am wonder what size resistors you recommend using for the R2 and R1.

We selected RSNS =4mohm R2=2ohm and R1=8.2ohms using the LM5069 calculator worksheet.

 

Do you have an example of the recommended layout with the Sense Resistor Divider implemented?

Below is the recommended layout with out the sense resistor divider.

Thanks,

Bill
