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 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. The recommendation range of Vbr is 0 to 1.3V and normal dimming range is 1.3 to 1.5V. However each lamp has deferent characteristics, therefore care must be taken to check brightness with using lamp and DC to AC Inverter units combination to avoid flickering or other problems.
