Part Number: TPS25221

Hi team,

Could you please help my customer to check the schematic of TPS25221DBVR, and if there is any EMI issue in the circuit.
I think the schematic of TPS2522 is good, but I am not sure about the EMI part.
below is the schematic of TPS2522, this is for US 3.0 application.

1. For output cap, at least 10+0.1uF.

2. It's not DC-DC switching part, no need to worry about the EMI issue.

For TI's policy, I will first click resolved button.

If you have any other concern, contact me any time.

If you think resolved, please help click 'Issue is solved button'.

Thanks.
