When placing orders, please confirm "Specifications" or Product Drawing" through TDK sal es or distributors. TDK is now under developing new DC to AC Inverter CXA-0345 which is designed for automotive LCD use. The architecture includes automatic brightness control with NTC themistor in cluded in the LCD for wide operate temperature as -30 to 85 deg-C. The CXA-0345 will distribute 6.5mA rms. under the normal conditio n, and 9mA rms between -30 to 50 deg-C. (Reference LCD is LQ065T9DR51 made by Sharp) A complete dimming interface with minimum and maximum setti ngs provide a approximately 10% to 100% flexibility. Wide input voltage is available from 8V to 16V and protection circu it will cover reverse input or serge. [1] Outline Label (Examlpe) TDK part No, Date code, Country of origin 1-1.

For circuit connection, please prefer to test circuit diagram [4]. Note2. Please use minimum of 2mm clearance (all directions) between inverter high voltage area and any conductors. Please refer to mechanical drawing for mark ing of high voltage area. Note3. Open voltage (strike voltage) is measured across the transformer secondary wi nding at no load as the reading at the output connector would be less than the actual value. Note4. 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 abn ormal operation due to coupling/leakage capacitance of inverter high voltage area to any surrounding conductor. Note5. Please check your lamp characteristic for minimum operational current and set the limit point in your design to avoid flickering and/or abnormal operation. Note6. For proper operation of circuit protection (fuse or IC),Please use min imum of 3A capacity for input power supply. Note7. Since these technical data are development targets, we cannot guarantee the characteristic of a product. Note8. Specifications sometimes become changes by this sampl e for the development goods.
