Hi,
When I do not use USB input, may I make PSEL open?

Hi PAN-M,
PSEL should tied high or low not left floating. A non-USB power source has higher output power capability so I recommend setting PSEL=GND.

Hi Jeff,
I do not use the USB pin (I use only the IN input.), still should PSEL connect with GND?

Hi Pan,
PSEL has no effect on IN pin, only USB pin. You can leave floating.

Thank you.
