I went through the application note snva829 page 2 and 3, the circuit in figure one is a traditional CC CV circuit, but I did not understant what is the relationship between the current flowing through the sense resistor and the output current? equation 1 is just a final equation,. I want to understand how does the controller circuit composed of the OPAMP, the transistor and RFB (the feedback resistor) work ? what is the current through RFB in terms of the sense current ?
