TPS56637: Start-up waveform when EN=floating

Hi team,

I'd like to check how start-up waveform look like when EN=floating.

I know it should behave like EN is always on, so will the start up waveform look like Figure 30 in the datasheet?

Or, can internal pull up circuit cause some delay depending on VIN?

Specifically, I'd like to know what happens when input voltage gradually ramps up from 0V to 24V.

Best regards,

Itoh
