TPS63020 Dynamic Input Current Limit vs Temperature

Can you show the TPS63020 change in the maximum average inductor current versus temperature (Dynamic Input Current Limit)?

    Maximum average inductor current will be at specified value of about 4A when die temperature is below recommend maximum operating temperature of 125C. When the temperature increases beyond that point Dynamic Current Limit will reduce current.  When die temperature reaches a 140C (typical value) the device enters thermal shutdown.  The rough shape of the maximum average inductor current curve is 4A above 125C decreasing linearly to 0A at about 140C.
