    Hi Zoey,

    Thanks for your patience. After review your schematics, I have several comments for your reference.

    1. Pay attention that PGND, AGND, DGND are all connected to a common GND together. I assume you already did in this way.

    2. It is better to connect PDN pin to DVDD with a pull up resistor of 10KOhm, 100KOhm is a bit too large.

    3. It is better to use output inductors with 10uH inductance in order to avoid large output ripples. Regarding the saturation current calculation, you can refer to "8.1.2 Inductor Selections" on page 77 and 78 of the datasheet. 

    Regards
