SETTING OUTPUT VOLTAGE
Line 1
------------------------------------------------------------
Line 2
The internal reference VREF is typically 0.6V. The output voltage is divided by a resistor divider,R1 and R2 to the FB pin.
Line 3
Vout = Vref x (1 + R6/R9)
Line 4
------------------------- AND ---------------------------
Line 5
Vout = Vref x (1 + R6/(R1+R4))
