BQ25601D: BQ25601D applied circuit noise generation inquiry and inductor inquiry

Part Number: BQ25601D

Hi, TI expert

A customer has an inquiry while testing the charging IC (BQ25601D).

Q1) A high-frequency noise is generated from the charging circuit during the charging IC operation.

Is there anything to be corrected in the attached circuit diagram?

Additionally, if you have a guide on what causes noise during normal charger operation, could you please let me know?

Q2) The inductor applied to BQ25601DEVM-877 is MPIM252010F1R0M-LF manufactured by Micorgate, but this product cannot be found through internet search.

Referring to TI E2E, IHLP1212BZER1R0M11 (refer to the attached datasheet) was checked and applied to the circuit.

Is the appropriate inductor selected? And are there any other alternatives (inductors) you would recommend?
