UCC28780EVM-002: Pin configuration

Part Number: UCC28780EVM-002

Hi

I am looking UCC28780EVM-002 based on GaN, and I find the RDM alue RTZ in schematics is absolutely different with the Mathcad calculation.

In mathcad, RTZ=174K,RDM=61.2K. But in Schematics, RTZ=249K, RDM=84.5K.

Why there is so large big difference?

Thanks.
