With the required output voltage setpoint at 5 V and VFB = 2 V (typical), calculate the ratio of R6 (RFB1) to R5 (RFB2) using Equation 9.
The resistor ratio calculates to be 3:2. Choose standard values of R6 (RFB1) = 2 kΩ and R5 (RFB2 ) = 3.01 kΩ. Higher or lower values can be used as long as a ratio of the 3:2 is maintained.
