TPS53311: Circuit does'n start with load.

Part Number: TPS53311


Hello, I'm using the TPS53311, and I have the following problem:When connecting with load (regardless of the load value) the IC does not start, it remains at 0V at the output. If I turn it on without load, and then put the load on, the Ci works normally. I'm not understanding this behavior. Could you please help me? Below is the electrical diagram.
