Hello,

Please see the following comments regarding the schematic:

FBVOUT1 appears to be connected to some resistor divider at the Buck1 output.
FBVOUT1 pin should be connected to the positive terminal of the BUCK1 output capacitors.
Pullup resistor on GPO3 (PS_POR_B) is typically recommended to be 100kOhm
Else, all other connections and values are fine.

Best Regards,
Sarah
