In the reference design of the TPS65994AD datasheet, the PP5V requires System 5V for power. If board is only used as sink, can I short PP5V to ground in this case? If so, do you have a recommend resistance value of the pull-down resistor?

Hello Anqi,
If board is only used as sink, can I short PP5V to ground in this case? If so, do you have a recommend resistance value of the pull-down resistor?
Yes, I would recommend around 100kΩ pull down resistor.
Best Regards,
Christian.
