Solana Beach, Calif. Taiyo Yuden (U.S.A.) Inc. has expanded its DC-AC inverter line for driving cold-cathode fluorescent lamps (CCFLs) in LCD backlighting applications with the introduction of the low-profile LS6D0812A-RH DC-to-AC backlight driver.
The high-efficiency LS6D0812A-RH is designed specifically for use with 10- to 15-inch 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 5-V (typ.) alarm output if the inverter detects a CCFL open condition in the LCD display systems.
The RoHS-compliant LS6D0812A-RH LCD backlight driver provides an input of 12 Vdc and an output current of 3-6 mA rms per lamp. The device's CCFL driving circuit includes a self-oscillating DC-to-AC converter, known as a Royer circuit, which minimizes electromagnetic interference (EMI). Total device power output is 3.5 W per lamp, or 7 W total.
The LS6D0812A-RH measures 6.02 (153 mm) x 0.85 (21.5 mm) x 0.39 inches (10 mm) H. (LxWxH). Other (typical) specifications include 1500 Vrms start-up voltage, 1 A maximum input current and wide operating and storage temperature ranges of -20° to 70°C and -30° to +85°C, respectively.
Pricing: $40.00 each in OEM quantities.
