CCFL DC-AC Inverters Are Economical

The Smart Force SFW series of dc-ac inverters includes economically priced generic converters for universal use across a broad range of CCFL-backlit LCD applications. For ease of selection, only 12 part numbers cover a wide range of applications. The SFW series come in single-, dual-, and multi-lamp configurations and can be used in LCDs from 5.7 to 19 in. in diagonal size in industrial, medical, and other applications. The devices feature profiles down to less than 6 mm high, and have strike voltages up to 2400 V rms. They have onboard lamp-current regulation, open-lamp detection, and dimming. The high-efficiency, RoHS-compliant inverters are compatible with virtually all OEM LCDs. Operating temperature range is ?20°C to 85°C. Prices depend on the part number and quantity. Typical distributor pricing for an SFWA160JF single-lamp inverter with 0.6-mA rms output current and a JST output connector SM02 (8.0) is under $10.00 in production quantities.
