DC/AC Inverter for Backlighting Two 10-15in Industrial LCD Panels
TAIYO YUDEN has announced the LS6D0812A-RH—the latest addition to its line-up of compact, low-profile DC-to-AC inverters for driving cold-cathode fluorescent lamps (CCFL) in Liquid Crystal Display (LCD) back-lighting applications. The high-efficiency LS6D0812A-RH is designed specifically for use with 10-15” industrial-grade LCD panels widely used in medical electronics, machine tools, digital signage, point-of-sale / kiosks, touch-screen and test & measurement equipment applications. The device provides dual LCD panel capability, and features brightness / backlight on-off control and a useful 5V (typ.) alarm output if the inverter detects a CCFL open condition in the LCD display systems.
Available now in OEM quantities, the RoHS-compliant LS6D0812A-RH LCD backlight driver provides an input of 12Vdc and an output current of 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 3.5W per lamp, or 7W total. Physically, the LS6D0812A-RH measures only 6.02” (153mm) L x 0.85” (21.5mm) W x 0.39” (10mm) H. Other (typical) specifications include 1500Vrms start-up voltage, 1A maximum input current and wide operating and storage temperature ranges of -20 to +70C and -30 to +85C, respectively.
