what's the relationship between the output current limit and input current limit of LTM8055?

"The maximum output current depends upon the input voltage. Higher input voltages yield higher maximum output current."

why? just because of the more input power with higher Vin?

the largest output current is 8.5A, so what's the largest input current of the module? is still 8.5A?

"Bear in mind that the maximum output current is limited by junction temperature, the relationship between the input and output voltage magnitude and other factors."

how can I design the current limit with the voltages not listed on the datasheet's graphs? like Vin=9V, Vout=10V, Iout=7.5A.

is there any formulas to calculate this precisely? 


all the conditions I mentioned above regardless of  the CTL, Rsense, etc.
