For circuit connection, please prefer to test circuit diagram. Note 2. Please use minimum of 2mm clearance (all directions) between inv erter high voltage area and any conductors. Please refer to mechanical drawing for marking of hi gh 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 va lue. Note 4. If the start up voltage falls below Cold Cathode Tube strike vol tage, the CCFL will not light up easily specially at lower ambient temperature. Please review mounting i nstruction to avoid any abnormal operation due to coupling/leakage capacitance of inverter high v oltage area to any surrounding conductor. Note 5. Please check your lamp characteristic for minimum operational cu rrent 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.
