LT8471 VIN Voltage

My customers are considering LT 8471.

So I got a question.


In the data sheet, it is described as follows.
"When either channel is configured as a buck, ZETA or single-inductor inverting converter, the corresponding VIN pin (s) must be boosted above the input voltage, VCC."


#1  Why is it necessary to set the VIN pin above VCC?
       As an application, cold crank etc. will not occur, but it will be configured as a buck or single-inductor inverting   



Best regards,
