Hi, Eggsy
As a best design practice, suggest you refer the EVM reference design.
Some comments:
1. For buck3: 5.8Vin --> 5Vout, what is max loading?
Based on experience, for 5Vout, Vin should be larger than 7V.
Because for big duty application, the high-side switch is ON more time in every cycle and high-side Rdson is big, so the thermal is bad.
So suggest Vin>=7V.
2. For input capacitors, suggest to refer the EVM schematic.
Place each 10uF cap for every Buck, and place near to PVINx pin in layout.
3. Suggest 2*22uF for every output.
