Parameter guideline for CCFL Inverter
Note 1: The below are AUO recommended Design Points.
Note 2: It should be employed the inverter which has “Duty Dimming”, if ICCFL is less than 4mA.
Note 3: CCFL discharge frequency should be carefully determined to avoid interference between inverter and
Note 4: The frequency range will not affect to lamp life and reliability characteristics.
Note 5: CCFL inverter should be able to give out a power that has a generating capacity of over

*1 All of characteristics listed are measured under the condition using the AUO Test inverter.
*2 In case of using an inverter other than listed, it is recommended to check the inverter carefully.
*3 In designing an inverter, it is suggested to check safety circuit very carefully. Impedance of CCFL, for
