It seems to regulate voltage at VFB to approx 1.4V. Using eq.2 and fig.17 I cannot set output voltage to 2V using R1 = 16.1k and R2 = 10k. This setting results in VOUT=4V.

The internal reference voltage is 0.765 V. Using R1 = 16.1 k and R2 = 10 k will result in Vout = 1.9955 V. Where do you see any reference to VFB = 1.4 V?
