LM5143: found in 15A when the overcurrent protection

Part Number: LM5143


dear

 

When I used LM5143, I configured the current parameters according to the 700W DEMO; then I used the 3.5 MΩ resistor according to the specifications, and the theoretical current limit was about 20A:

But in the actual test, found in 15A when the overcurrent protection, how to optimize the design?thanks
