Intensity control is accomplished by the user providing a DC voltage level at PIN 6 of CON1. Enable control is accomplished at pin 5 of CON1. A +5V reference voltage is available at PIN 7 of CON1 for external use. The PWM dimming frequency of the inverter can be synchronized to the LCD frame rate via PIN 8 of CON1. All outputs are open and short circuit protected. MECHANICAL/ENVIRONMENTAL Weight = 20 grams Altitude = 10,000 ft max. Humidity < 85% non-condensing Size (L x W x H) = 5.4 IN x 0.7 IN x 0.357 IN PCB thickness = 0.062 IN Mounting Holes = 0.120 IN diameter (X2) Input Power & Control Connector = CON1 CCFL Output Connectors = CON2 and CON3 Page 1 of 2 AC3-12-1902 397 Route 281 P.O.
