I designed a 5.2 VDC DC with TPS63806.
When I applied 5V to test the board, the TPS63806 started to heat up and eventually stopped working. When I checked it with a tester, I found that the DCDC Vin and GND were short-circuited.
Schematics and layouts cannot be shared here. If a TI engineer can help, I will send you a schematic and layout diagram in DM.
