    Hello Mark,

    At a high level, tSETx and tSETy are the settling time of the device. This can be thought of as a deglitch timer for the device as it confirms if the new power rail is stable and higher than UVLO. This is directly proportional to the SS capacitor used but we do not spec this time on the datasheet. It is used during any initial startup event that the device goes through but not during switching between two validated rails.
