LTC3803 loop compensation

Is there some indication on how the feedback loop on the LTC3803 parts should be done? at least some starting point.
The datasheet says that an RC series has to be connected to ITH/Run but I have never seen a compensation network between the output and the ground, only on the feedback loop).

Any kind of reference could be helpful

    Please consider LTC3803 datasheet, ITH pin

    ITH/RUN (Pin 1): This pin performs two functions. It serves as the error amplifi er compensation point as well as the run/shutdown control input. Nominal voltage range is 0.7V to 1.9V. Forcing this pin below the shutdown threshold (VITHSHDN) causes the LTC3803 to shut down. In shutdown mode, the NGATE pin is held low
