Hello Jeffery,

The difference between the startup times is due to the startup behavior of the devices. ISOW7842 will start switching after UVLO is exceeded and the ISOW7742 requires some additional set up time which is shown in the datasheet at 7.3 Recommended Operating Conditions below.

Best,
Andrew
