Dear Sir,

I used BQ25703A.

Would you let me know my schematic is wrong or not?

Thank you.

    Hey Sean,

    The RIADPT resistance should be 137kOhm+/-3% for a 2.2uH inductor.

    Also, the RC filter on the ACP and ACN pins is recommended to be 4.99Ohms and 33nF. You currently have 10nF and 10Ohm. 

    I would also recommend checking your capacitor voltage ratings. 

    Regards,
