If the EN pin is driven to 2.5V while VIN floats, does any damage occur to the part; Is there any chance there would be backflow current from EN to VIN?

Hi thunderjackson,

Yes, you can force a voltage on EN, while VIN is floating, as long as the EN pin and all other pins are within the absolute maximum ratings as defined in the datasheet.

Best Regards…
