Hi Jimmy,

1. The input caps are too small. Please change C99/C100/C101/C102 to 22uF/25V

2. Separate PGND and AGND. Use a 0ohm resistor or Net tie to connect PGND and AGND together.

3. R81, R85 should be connected to output sense point (not local sense) and also connect to VOSNS and GOSNS. Please refer to Fig 8-1 in the datasheet.

Hope this helps,

Thanks,

Nancy
