LMR33630-Q1: Operation at start-up(softstart)

Hi team,

My customer asks us how the LMR33630 behaves when IC was reenabled in the conditions keeping intermedia VO voltage.

It has high sink current flow from VOUT to GND through LS-FET?  Or  it shows prebias operation by putting LS-FET in off state?

Best regards,
