(Backlight current in AD24 measured to be 55mA, and we desire to match AD49 backlight brightness to AD24)
(Vbe was measured in a VC0 sample to be .66V, so that voltage will be assumed to be nominal)
R10 = (Vbe / I) = (0.66V / 55mA) = 12 Ohms
2.35V * 55mA = 130mW
6V (DC input) - 0.3V (Schottky Diode) - 0.6V (R10) - 2.75V (white LED backlight) = 2.35V
Max dissipation will be about 130mW:
