Hi Minki,

Please share the schematic.

Yes, you can turn ON/OFF the device with EN pin

Hi Minki,

Please find my comments below.

EPAD should be kept floating
SLEEP_OV needs to be left floating if not in use.
You can scale down your gate resistors to 10ohms each.
You can scale down your charge pump cap to ~1uF, 2.2uF is an overkill and will increase your startup time.

Rest, the schematic looks fine.
