TPS628501-Q1: inrush current during startup

Part Number: TPS628501-Q1

Hello team,

To consider the current rating of the buck converter in front of the TPS628501-Q1, we would like to know the inrush current during  start up.

Do you have any good idea to estimate this?

Do you have a waveform of the inductor current during startup?

The schematic is not decided yet.

Vin=3.3V, Vout=1.1V, Cout = TBD

Thank you.
