TPS24751: Use of R/C on output for high In-rush current load.

Part Number: TPS24751

I am trying to power a large LCD 12V/8A(nom) LCD display from the output of the TPS24751 circuit.

The LCD can have as much as 26A in-rush current when the backlight powers up.

This is over an approximate 3ms period.

Would it be prudent/advisable to change/set the Dv/Dt rise-time on the output by adding the RC to the Gate control output pin of the TPS24751?

If so, what values would you recommend?

Thanks in advance.
