LCD Backlight Driver Sports Ultra-Low Profile And Wide Dimming Range

XSDesigned for brightness control in LCD backlighting applications, the Model LS650 is an ultra-compact CCFT (cold cathode fluorescent tube) inverter. Measuring 105 mm x 25 mm x 10 mm, the LS650's rigid construction and compact, low-profile design is said to help manufacturers of industrial instruments and test and measurement equipment meet continuing design miniaturization requirements. Employing a single transformer and dual output, the LS650 has an input range of 11.4 to 12.6 Vdc and a total output of 4W for two lamps. A 5V input model is also available. A brightness control permits dimming adjustment of 20% to 100% by applying a dc bias voltage of 1.5V to 1.9V or by means of a 0½ to 10 K½ variable resistor. Pricing is $15 each in OEM quantities.
