DC-AC INVERTER UNIT CXA-0323 SERIES (3.0W SINGLE OUTPUT) (PRELIMNARY, Custom Design) DESCRIPTION : This DC-to-AC inverter is developed for Sharp Display LQ038Q5DR01. The output current of the inverter is reduced to prolong CCFL life time. The inverter is equipped with a dimming input which permits CCFL brightness control by applying an external PWM signal. APPLICATION: FEATURES : Single lamp type Lamp Voltage 530V Lamp Current typ. 4 mA High Efficiency (typ. 85%) Fuse protection Ext. PWM Dimming with internal Pull-Up 1,5 kohm Low noise with voltage resonant circuit CXA-0323 1 4 mm diameter 2.2±0.2 16±0.2 3 1 max 2 8 max 1 CN2 1 (2) 80.5 max 60±0.2 (8) CN1 20.5max 14±0.2 (3) TEMPERATURE & HUMDITY : Operating Temperature Range 0 °C ~ +60°C Storage Temperature Range -40 °C ~ +85°C Humidity 95 %RH max MAX.
