Step Four: Set the Output Voltages

Set the output voltage levels. for V0, V1, V2 and V3 pins ).

  • VID 00, V0 = VSET1 = 0 V
  • VID 10, V2 = VSET2 = 1.1 V
  • VID 01, V1 = VSET3 = 1.65 V
  • VID 11, V3 = VSET4 = 1.8 V

The resistor value:

  • VREF = 2 V
  • R1 = 20 kΩ
  • R2 = 15 kΩ
  • R3 = 54.9 kΩ
  • R4 = 110 kΩ
  • R5 = 0Ω
