LTC3897 Boost Controller Voltage Input Range

I want to use the LTC3897 Boost Controller with input range from 9V to 32V and an output of 48V.
I have the DC2108A Demo Board which supports inputs from 16V to 55V and output of 48V.


There is a reference design in the LTC3891 datasheet that claims to support inputs from 6V to 55V with output of 48V, but that design seems very similar to the demo board circuit. I cant figure out what parameter determines the input voltage range.
