2 The specifictions my e chnged without ny notice. When plcing orders, plese confirm "Specifictions" or Product Drwing" through TDK sl es or distriutors. TDK is now under developing new DC to C Inverter CX-0345 which is designed for utomotive LCD use. The rchitecture includes utomtic rightness control with NTC themistor in cluded in the LCD for wide operte temperture s -30 to 85 deg-c. The CX-0345 will distriute 6.5m rms. under the norml conditio n, nd 9m rms etween -30 to 50 deg-c. (Reference LCD is LQ065T9DR5 mde y Shrp) complete dimming interfce with minimum nd mximum setti ngs provide pproximtely 0% to 00% flexiility. Wide input voltge is ville from 8 to 6 nd protection circu it will cover reverse input or serge. [] Outline -.

For circuit connection, plese prefer to test circuit digrm [4]. Note2. Plese use minimum of 2mm clernce (ll directions) etween inverter high voltge re nd ny conductors. Plese refer to mechnicl drwing for mrking of high voltge re. Note3. Open voltge (strike voltge) is mesured cross the trnsformer secondry winding t no lod s the reding t the output connector would e less thn the ctul vlue. Note4. If the strt up voltge flls elow Cold Cthode Tue strike voltge, the CCFL will not light up esily specilly t lower mient temperture. Plese review mounting instruction to void ny n orml opertion due to coupling/lekge cpcitnce of inverter high voltge re to ny surrounding conductor. Note5. Plese check your lmp chrcteristic for minimum opertionl current nd set the limit point in your design to void flickering nd/or norml opertion. Note6. For proper opertion of circuit protection (fuse or IC),Plese use min imum of 3 cpcity for input power supply. Note7. Since these technicl dt re development trgets, we cnnot gurntee the chrcteristic of product. Note8. Specifictions sometimes ecome chnges y this smpl e for the development goods.
