San Marcos, Calif.—Taiyo Yuden's KLS-150A is a compact single-board DC/AC inverter for driving two cold-cathode fluorescent lamps (CCFL) in backlighting applications for selected Sharp and Optrex liquid-crystal displays (LCDs). Typically suited to medical and industrial equipment requiring super-bright, high-visibility displays, it's rated for operation in harsh environments (0 to +60°C).
The dual-lamp PWM driver delivers 6.5 watts per lamp from a typical 12-volt (10.8 to 13.2 volts) input for the Sharp 15-inch LQ150X1LGNA, Optrex 12-inch T-51866D121J-FW-A-AA, and Optrex 15-inch T-51863D150J-FW-A-AA LCDs. Specifications include a start-up voltage of 2100 VRMS, 930 VRMS output voltage, and 50 kHz output frequency.
