Hi,

In TPS55340 D/S description, NC pin must be connected to GND.

If we leave NC pin open, what kind of problem will occur?

Thanks,

The NC pin is connected to an internal circuit that is disabled. Nothing will likely happen if this pin is left floating as this circuit is disabled, but grounding it will gaurantee it has no impact on the operation of the IC.
