    Hello,

    I noted some components that are included on the EVM schematic diagram that are not on your schematic, or that are different. 

    Please refer to the user guide for reference on these components: http://www.ti.com/lit/ug/sluubg6/sluubg6.pdf

    First I noted the RIADPT resistance. This value should follow the Table 3. Inductor Setting on IADPT Pin in the datasheet of the charger.

    Second, the SRN and SRP nodes are missing crucial caps, or are incorrectly sized. Again, please refer to the EVM schematic to place the correct capacitance on the two sides of the sense resistor.

    Regards,
