Hi Kevin,

Greeting!

You can refer to the below description in our datasheet, the root cause is the requirement in HUB application, if you are not the HUB application, just need one 10uF and one 0.1uF are ok, thank you.

Best Regards,

Kuno

Hi Kevin,

It seems for the Inrush Current limit, you can refer to the below USB2.0 spec. Thank you.
