TPS2553: Current limit does not work

Part Number: TPS2553

Hello,

I am testing TPS2553 current limit function, I tried to sink current from 0A to 1.8A by Eload CC mode, and the expected result is the current limit around 1.8A with a certain voltage. But it seems not. Does any one help me clarify this issue?

My Rlimit is set to 15k ohm, and the curve is as attachment. (Yellow is Vin, Blue is Vout, green is FAULT, and red is the current (1A/1V))

One more question, why there are any pulses after a while?
