TAIYO YUDEN Introduces DC-AC Inverter For Backlighting Two 10-17" Industrial LCD Panels

March 03, 2009 by Jeff Shepard

TAIYO YUDEN (U.S.A.), Inc., announced the LS6D-1012A-RH – the latest addition to its extensive 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. Designed specifically for use with 10-17" industrial-grade LCD panels, the LS6D-1012A-RH provides dual LCD panel capability. It features brightness / backlight on-off control.

This high-efficiency device is widely used in medical electronics, machine tools, digital signage, point-of-sale / kiosks, touch-screen and test & measurement equipment applications.

The RoHS-compliant LS6D-1012A-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 5W per lamp, or 10W total. Physically, the LS6D-1012A-RH measures only 7.09" (180mm) x 1.46" (37mm) W x 0.39" (10mm) H. Other specifications include 1500Vrms minimum start-up voltage, 2A maximum input current and wide operating and storage temperature ranges of -20 to +70°C and -30 to +85°C, respectively.

The units are priced at $38.80 each at OEM quantities with a delivery of 16 weeks ARO for large OEM orders.
