CXA-0323

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: 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 FEATURES : TEMPERATURE & HUMDITY : Operating Temperature Range 0 °C ~ +60°C Storage Temperature Range -40 °C ~ +85°C Humidity 95 %RH max MAX. RATING: Input Voltage: min. 9,6 Vdc; max. 14,4 VDC (the output current is different) Output Power: max. 3,5 Watt DIMENSIONS : 80.5 max 60±0.2 (3) 20.5max 14±0.2 16±0.2 3 Note Typ. 4 mArms (2V) 1 max 8 max VER, 22/08/2001 1 CN1 2 1 4 mm diameter 2.2±0.2 No. Part Description Qty. 1 1 PWB Connector CN1 1 2 Connector CN2 1 3 Note UL94V-0 53261-0590 t=1mm (Molex) (JST) CN2 : SM02(8.0)B-BHS (JST) SM02(8.0)B-BHS CN1 : 53261-0590 (Molex) Pin CN1-1 CN1-2 CN1-3 CN1-4 CN1-5 Symbol Vin GND Ext.
