Taiyo Yuden DC-AC Inverter drives LCD Panels
TAIYO YUDEN has announced the LS6Q-1612A-RH, a compact, low-profile DC/AC inverter for driving cold-cathode fluorescent lamps (CCFL) in Liquid Crystal Display (LCD) back-lighting applications. Designed specifically for use with 12-17in industrial-grade LCD panels, the LS6Q-1612A-RH provides dual LCD panel capability. It features brightness / backlight on-off control and a 5V (typ.) alarm output (if the inverter detects a CCFL open condition of the LCD display systems).
ThisAvailable now in OEM quantities, the RoHS-compliant LS6Q-1612A-RH LCD backlight driver provides an input of 12Vdc and an output current of 3.3-6mArms per lamp. The device’s CCFL driving circuit includes a self-oscillating DC-to-AC converter, known as a Royer circuit, which minimizes EMI compared to other control methods. Total device power output is 4W per lamp, or 16W total. Physically, the LS6Q-1612A-RH measures only 5.91” (150mm) L x 1.97” (50mm) W x 0.39” (10mm) H. Other specifications include 1500Vrms start-up voltage, 2A maximum input current and wide operating and storage temperature ranges of -20 to +70C and -30 to +85C, respectively.
