LM5171EVM-BIDIR: Utility of a low pass RC network on the sw1 pins of the LM5171 component

Tool/software:

Hi,

I notice that there are two RC networks connected to the SW1/SW2 pins of the LM5171 in the schematic of the LM5171 EVM evaluation board. I have not found any recommendation of these networks on other design documents. The datasheet does not show this filter on the application examples nor on the Webench tool nor on the Boost Quickstar tool spreadsheet of the LM5171.

What is the role this RC networks on SW1 SW2 pins? are they critical?

Thanks you very much for your help.

Regards,

Bruno
