LTC4000 and DC/DC

Hi

I plan to use LTC3703 with LTC4000.(Back converter)

Condition is similar to below URL.  

https://ez.analog.com/power/f/q-a/99238/ltc4000/297154#297154

I have question  for ITH connection.

①LTC3703 have COMP pin for compensation.

 And DC/DC is required a control pin or external-compensation in LTC4000 datasheet.

 I think that ITH connect to comp pin.

 Is it right?

②LTC3703’s  compensation is TYPE1-3.

   That's different from Vc pin.(LT3845A)

   Are ITH required both CC pin compensation and TYPE1-3?

   Which connection is right   ITH-FB or ITH-COMP (below A or B?)

   

Best regards
