CXA-0345

DC-AC INVERTER UNIT CXA-0345 (8W Automotive LCD) DESCRIPTION : TDK designed a new DC to AC Inverter CXA-0345 which is designed for automotive LCD use. The architecture includes automatic brightness control with NTC thermister included in the LCD for wide operate temperature as -30 to 85 deg C. The CXA-0345 will distribute 6.5mA rms. under the normal condition and 9mA rms between -30 to 50 deg C. (Reference LCD is LQ065T9DR51 made by Sharp) A complete dimming interface with minimum and maximum settings provide a approximately 5% to 100% flexibility. Wide input voltage is available from 8V to 18V and protection circuit will cover up to 25V and reverse input or serge. Lamp Voltage 600～800V Lamp Current 9.0mA max FEATURES : Wide Input Voltage Wide Dimming Range (By Internal PWM Control Circuit) Low noise with voltage resonant circuit No High Voltage Pattern on Bottom Side High Efficiency 8mm Low Profile. Fuse Protection TEMPERATURE & HUMDITY : Operating Temperature Range Storage Temperature Range Humidity (PRELIMINARY INFORMATION) -30 deg°C ~ +85 deg°C -40 deg°C ~ +85 deg°C 95 %RH max (A maximum wet ball temperature is 38 deg°C) Label (Examlpe) TDK part No, Date code, Country of origin DIMENSIONS : (4) 120±0.5 107.7±0.3 (6.0) 23.7±0.3 1 1 CN3 (2) CAUTION HIGH VOLTAGE 3.0±0.3 4-φ 2.5 (3) 8.5 Max (1) Power Systems – The Power Solution Web: Email: www.Power-Systems.de Info@Power-Systems.de Page (1 / 3) Address: Dörnet 8 ; 74360 Ilsfeld-Auenstein / Germany Tel. : + 49 / 70 62 / 67 59 - 6 Fax: + 49 / 70 62 / 67 59 - 80 VER, 31.
