Document 293 -1 CCFL Transformers FL3209 parts have been improved. The new FL3209-5L and FL3209-6L are electrically equivalent to the FL3209-1L, FL3209-2L, FL3209-3L and FL3209-4L, and have an improved physical design. We will continue to support existing customers of the superseded parts. The FL Series of transformers is designed for use in cold cathode fluorescent lamp (CCFL) power supplies at operating frequencies up to 100 kHz. With output power from 3.5 to 6.0 Watts, these transformers are ideal for LCD backlight applications. They are available in two different gull wing, surface mount packages and one inboard configuration for height restricted designs. Free evaluation samples are available by contacting Coilcraft or ordering them on-line at www.coilcraft.com.
