TPS563209: Reverse polarity behaviour and protection

Part Number: TPS563209

Hi there, what will the converter IC do if power is applied in reverse polarity? If it will malfunction or fail, what is the best way to protect?

I am using the reference EVM design PCB layout for a Vin of 12V (automotive) and output of 5V at approx 2.5Amps.

If reverse polarity protection is required, would a simple diode on the output stage after the feedback resistor work ok?

Thank you
