I am trying to use the LM25011 as shown in the webench schematic above. It will work fine at 12.5V in with a 600mA load, and 16V in with the same load, but if I increase the input voltage from 12.5 to 16 while it is running, the FET shorts and Vout just tracks Vin. What would likely be causing this failure?
