Insufficient Information About Datasheet


I designed lots of topology about DC-DC converter. But some IC have not enough information to compansate my systems.  For example, Lots of datasheets dont include "Current Sense Amplifier Gain" and "Vslope (Compansating regulator voltage)". Now, I am using LT8228, LT3845A and LTC3779 for my design. At least, Could you share with me related information for these IC?
