FL2015-10L

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 We will continue to support existing customers of the superseded parts.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 opTurns ratio Part number1 Schematic Package pri : sec pri : fb FL2015-1L_ FL2015-2L_ FL2015-3L_ FL2015-4L_ FL2015-5L_ FL2015-6L_ FL2015-7L_ FL2015-8L_ FL2015-9L_ FL2015-10L_ FL3209-5L_ FL3209-6L_ FL2810-1L_ B A A A A B A A A A C D C 1 1 1 1 1 1 1 1 1 1 5 5 4 1 : 67 1 : 67 1 : 100 1 : 50 1 : 125 1 : 67 1 : 67 1 : 86 1 : 100 1 : 93 1 : 100 1 : 93 1 : 100 1 : 0.19 1 : 0.19 1 : 0.25 1 : 0.14 1 : 0.38 1 : 0.19 1 : 0.19 1 : 0.21 1 : 0.25 1 : 0.25 — 1 : 0.17 — erating 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.
