We have a design with an EP53F8QI that multiple ICs have been burned both at room temperature and +80 °.C. We are using it to create a +3.3V and on fault we have found that the +3.3V supply is shorted to GND. We have checked all the capacitors and resistors and they are according to the spec outlined in the data sheet. The only thing we could found is that the GND plane was not routed directly underneath the layer on which the IC was placed much further into the PCB. Is there someone who can help me with this issue ?
