hello
Can you Review the schematic for below specifications?
VIN : 4.8 ~ 5.8V
Output Voltage : 0.85V (+- 0.025V)
Output Current : 25A ~ 30A
OP Temperature : -40 ~ 80℃
Regards.

Hello,
Here are the comments:
1. R354/R355 can NOT be populate. Otherwise, it will short.
2. C213/R350: I found 1nF and 1ohm better suppress the high frequency noise. It is optional to change when you evaluate the performance.
3. Input capacitor: change C208 =100nF or add 100nF and place next to pin 20 and 21. This cap will help reduce the high switching frequency noise.
4. R346: The setting is 1ms startup. However, I saw 4mF at the output capacitance. I am NOT sure you actually plan to use all 3x1000uF populate or not. Just concerning on the inrush current
