TPS54620 Over Current Protection foldback?

Other Parts Discussed in Thread: TPS54620, TPS62180, TPS54622

Hi,

I use in my design a DC-DC converter TPS54620, and am interested in testing its current limiting operation in short circuit mode.

My test setup is as follow:
 - Creating a short circuit between Vout and GND.
 - Placing a DVM (in current mode) between TPS54620 output pin, and short circuit.
 - Measuring output voltage during operation via scope.
 - Temperature measurement with a thermo-couple measurement device.

Test results are as follow:
 -  Output current is at 9.4A (steady).
 - Output voltage is ~150mV.
 - Temperature reached := 94 degree Celsius (after prolong operation).

My questions are:
 - Can the output current limit be lowered?
 - Why there is no fold-back operation (as shown in the attached -  right graph), whereas my unit behaves like the left graph)?

Can you help me with the above?

Thanks,
Refael.
