Hello Ren Nakayama,

OVP ; Not use, if OVP is connected to GND, device will enable factory set over voltage trip level.

PGOOD ; Not use

PGTH: connect to GND, if PGOOD functionality is not required.

if you dont need reverse current blocking, you can consider using TPS1663 device.

Please refer to schematic in user's guide : TPS16630-32EVM Evaluation Module for TPS1663x (Rev. A)
