Part Number: LM20154 Please let me know about two points below about LM20154 design.
①Datasheet P2 is described about "NC pin must be connect to GND".
What is occur abnormal operation on NC pin floating condition?
Is LM20154 occur only noise…
Part Number: LM20154 Tool/software: WEBENCH® Design Tools I attached Webench design for LM20154, simulation results was Vout oscillation.
If there found correction points or any bug, please let me know.

We are seeing failures of this part where the PVIN shorts to gnd and the part smokes. The NC pin (5) in the design is floating. Could this cause failure?
