LM5116: Turn ON with load

Part Number: LM5116

Dear Sir,

I am facing issue while turn ON of the buck converter with full load (10A), the output voltage is dipping from 12V to 6V or less.

But if I turn on the load after converter is ON completely, there is no issue it is able to take 20A load also with proper regulation.

I guess the current limit is engaging, if I am turning On converter in  full load (10A resistive load). I am facing problem in only turn On time.

How this turn On with load issues can be solved. I tried increasing the SS capacitor also to 100nF, its not helping.

Thanks and Regards,

Nesh
