    Hi Wenjun,

    Yes the same EN voltage as the VIN voltage is recommended. You can also have a separate rail voltage as long as it does not exceed VIN voltage and is at least 65% of VIN for enabled state and below 35% of VIN for disabled state. The EC table values you highlighted are percentages of VIN voltage.

    Thanks,
    Joshua
