TPS55288EVM-045: Evaluation board issue

Part Number: TPS55288EVM-045
Other Parts Discussed in Thread: TPS55288

I was successfully testing the evaluation board at 14V in, 10.8V output, at 3 amps, when it suddenly switched off.
I removed the board from the test environment, and attached to a bench power supply. Upon resupplying power, the supply was overloaded. When checking with a multi meter, the input and output resistance to ground is now effectively 0.
I was very happy with the board, and would like to continue evaluation of this design, but I am not sure how to diagnose the damage, or what needs to change to prevent it. Any suggestions, or recommendations would be appreciated.
