Please teach us a way of thinking of UCC28050's Vcs .
Page 7 of the data sheet of this device has a calculating formula for the threshold of the VCS.
VCS≒0.67*(COMP - 2.5V)(MULTIN + VOFFSET)
At the time of COMP=2.4V, how does VCS turn out?
Does not the calculation result of (COMP-2.5V) become the negative value?
Or is a way of thinking that VCS becomes 0 right when (COMP-2.5V) is the negative value?
