Tool/software: WEBENCH® Design Tools
I'm experiencing repeated catastrophic failure of the TPS54360 when it is plugged into an active power source.
In particular, I have the TPS54360 setup to convert 48V DC to 6.5V DC for power over Ethernet. When the Ethernet cable is connected with the system off, turning on the power supply results in normal operation. However, when the Ethernet cable is connected after power is already supplied to the system, the TPS54360 fails dramatically. This happens with some regularity, though not every time the device is hot plugged. I have been able to reproduce this behavior.
I'm using a recommended WEBENCH configuration for the TPS54360 and a Mean Well supply for the 48V. Any recommendations about the potential problem (and how to solve it) are appreciated.
