Note 1.
For circuit connection , please prefer to test circuit diagram.
Note 2.
Please use minimum of 2mm clearance (all directions) between inverter high voltage area and any
conductors. Please refer to mechanical drawing for marking of high voltage area.
Note 3.
Open voltage (strike voltage) is measured across the transformer secondary winding at no load as the
reading at the output connector would be less than the actual value
Note 4.
If the start up voltage falls below Cold Cathode Tube strike voltage , the CCFL will not light up easily
specially at lower ambient temperature . Please review mounting instruction to avoid any abnormal
operation due to coupling/leakage capacitance of inverter high voltage area to any surrounding
conductor.
Note 5.
Please check your lamp characteristic for minimum operational current and set the limit point in your
design to avoid flickering and/or abnormal operation.
Note 6.
For proper operation of circuit protection (FUSE or IC PROTECTOR), please use minimum of 2A
capacity for input power supply.
Note 7.
A start up sequence of Vrmt is the sametime of Vin turning on or after
Note 8.
CN1-3 has brightness and remote functions. These functions are operated by voltage of Vbr as below:
Luminance is max. at Vbr = 0V; Luminance is min. at Vbr = 3.4V
Vbr ≥ 4.75V ⇒ No operation (Vrmt = 5~7V)
