LM5117: LM5117 Constant Current Stabilization Problem

Part Number: LM5117

Hi there,

I am designing a circuit for one of my projects with LM5117. My intend was to create a CC regulator with hiccup mode OVP which exists in the datasheet of LM5117.  

And then i made a design with this configuration. The configuration i did is below:

 

But when i run the simulation, there is unstability in the inductor current. The photo is below. 

I tried to set the output current to 4 Amps. This is also a problem but i do not care it at the moment. It does not set to another value also. I think this behaivour of IC is not natural.

Could you please help me?

Thanks.
