TPS54060: UVLO limits

Part Number: TPS54060

Team,

I need to design a buck for an input range of 4V to 35V. Can you advise me what resistor values need to be used for EN? Seeing that the max voltage on that pin is 5V, is there any way I can avoid using an external EN source?

Thanks,

    On page 3 of the datasheet, pin functions, it mentioned that the pin can be left floating to enable the part. If you don't need external sequencing or controlled higher EN threshold than default, you can leave the pin floating. There's an internal current source to pull up the pin if floating.

    Regards,
