Table 4-1 GPIO Parallel Feedback Resistor Network Truth Table
GPIO1 GPIO2 GPIO3 FB Top (kΩ) FB Bot (kΩ) Vout (V)
0 0 0 100 24.9 5.016
1 0 0 100 12.45 9.032
0 1 0 100 7.135 15.016
0 0 1 100 5.248 20.054
Note:
  1. Vout calculation is based off nominal top and bottom feedback resistor and does not account for part tolerance and variation.
  2. GPIO entry are logic level values where "1" means voltage applied and "0" means no voltage applied.
