Recommended Operating Range
Maximum power consumption
Where
segment current = 3mA, grid current = 15mA, and LED current = 20mA
VFD driver dissipation = number of segments x 6 + number of grids/(number of grids + 1) x 30(mW)
R
LED driver dissipation = number of LEDs x 20 (mW)
Dynamic power consumption = V
