Burnt FB63 due to power surge

[girish7]

i burnt the fb63 and now NRF52840 is not able to power up.  even desoldered the FB63 and put a short on the particular pads. THe eval board is still not able t power up. Is there any other way to power up the board?

I checked the voltages, VDD is not generating. VBUS is reading 5V.

Hello,

You have likely damaged the board (it's quite a lot of current that must have passed through the FB for it to be damaged, likely you have had current/voltages other places also at the same), so I don't see any way around buying a new nRF52840-DK in this case.
