Hi,
So I don’t see any immediate discrepancies in your layout and schematic. But there could be a difference in board layers and other PCB layout factors
It seems the FET might be getting extremely hot because your output power is nearing 100Watts. Could you measure the temperature of the boost converter and FET?
Is the concern with the high temperature because the part will shutoff or something else?
Are you getting the desired output on your PCB and the EVB?
Also, reading the EVB datasheet, it looks like the board is designed to only handle 3 to 10Vin. Whereas it seems you’re inputting in 12V.
Did you make modifications to handle this change?
Thanks,
Cindy
