LM25116: Is there any other setting which will impact the over current detection except for the current sense resistor?

Hi,

My customer checked with me ,except for the current sense resistor, is there any other setting or factor will impact the over current detection?  thanks.

    Hi 

    LM5116 Datasheet fig31 and formula(5) in page 18 mentioned the Ipeak=[1.1-(25uA*ton/Cramp)]/(A*Rs)

    so the A is relate to the input resistor of CS and CSG,  and Cramp is simluated the raise current of the inductor. these two factor also will impcat over current detection

    and the cap between CS and CSG if you added is third factor

    Thanks
