Only the loop controller device needs a resistor divider at the VSEL pin to program the output voltage. The VSEL pin of loop follower devices are not used. The resistor divider code selected for this 1.2-V output example using Table 8-12 is a single resistor to AGND. With the resistor divider code selected for the range of VOUT, select the resistor to AGND code with the VOUT_COMMAND Offset and VOUT_COMMAND step from the Table 8-13. With V_OUT = 1.2- V, VOUT_COMMAND_(Offset) = 0.5 V and VOUT_COMMAND_(STEP) = 0.05, the result is code 14. A 68.1-kΩ resistor to AGND at VSEL programs the desired setting.
