I am writing a test requirement document on a CCA the contains a LT3743. I have reached the part of my test that would require probing at pin 15 (RT) on the LT3743. I don't see any way to know what signal to expect there. I see a max of 3V from the datasheet but don't see anything else to help determine a value that should be seen there. The SYNC pin is grounded and a resistance of 84.5k ohms for RT. Any help would be appreciated.
