Lamp power consumption
1) Measurement circuit voltage at primary side: DC 12.0 V.
2) LCD: All digits White, VDD = 3.3 V, VEE - VSS = Vmax, D0 to 7 = ”H” (White), and
3) Ambient temperature: 25 °C.
The ratings are given on condition that the following conditions are satisfied.
*1 It is recommended that IL be not more than 5.0 mArms so that heat radiation of CCFT backlight may
*2 Power consumption excluded inverter loss.
*3 The circuit voltage of the inverter should be designed to have some margin, because kick-off voltage
*4 Life time of CCFT will be decreased when LCD is operating at lower temperature.
