Coilcraft, Inc. FL Series CCFL Transformers FL2015-1L FL2015-1LD

The FL2015-1L is a surface mount transformer designed for cold cathode fluorescent lamp (CCFL) power supplies operating up to 100 kHz, with an output power of 6.0 Watts. It uses a Royer topology and features a turns ratio of 1:67 primary to secondary and 1:0.19 primary to feedback. The transformer is housed in Package 1, measuring 24.77 mm by 20.96 mm, with a weight of 5.5 to 6.1 grams. It has a maximum primary DC resistance of 0.220 ohms, secondary DC resistance of 285 ohms, and feedback DC resistance of 0.10 ohms. The transformer supports a continuous secondary voltage of 1600 Vrms and an instantaneous startup voltage of 2000 Vrms. Isolation ratings are 1500 Vrms between primary and secondary, 500 Vrms between primary and core, and 1500 Vrms between all windings and core. The operating ambient temperature range is −40°C to +85°C.
