TPS5430DDA_Line Transient response issue

I am using TPS5430DDA in a daughter board and attached the TINA simulation design file for the same. As part of the requirement, when input surge voltage is applied, output voltage regulation is not met. Kindly check the same and suggest. In the attached file, 4.7mF input capacitor is given for the power supply holdup purpose and 330uF output capacitor will be present in the main board.
