I Study ADP5090 UG-708 "EVAL-ADP5090 User Guide" document. The Figure 4. ADP5090 Pin 4(R7) show NC But Table 2.Bill of Material show R7-Resistor, 20k. Which one is correct? If R7 is NC ADP5090 efficiency will not be affected and how much affect? if it is a Resistor, 20K its purpose is? how do I calculate this resistor values and the meaning of representative is?
