CCFL Transformer ForTexasInstruments
TPS68000 CCFL Controller
The FA2786-BL was developed specifically for the Texas
Instruments TPS68000 Phase Shift Full Bridge CCFL
Controller. It is designed for use in cold cathode fluores-
cent lamp power supplies operating at frequencies up to
100 kHz.
This transformer is specified in the Texas Instruments
TPS68000EVM-202 dual-transformer reference design.
This reference design shows a single TPS68000 driv-
ing two FA2786-BL transformers and CCFL lamps.
Isolation is 500 Vrms between windings and 2000 Vrms
from each winding to the core.
Free evaluation samples are available by contacting
Coilcraft or ordering them on-line at www.coilcraft.com.

1. When ordering, please specify a packaging code:
FA2786-BLD
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape (400 parts per full reel).
B = Less than full reel. In tape, but not machine ready. To
have a leader and trailer added ($25 charge), use
code letter D instead.
2. Inductance measured at 1 Vrms, 60 kHz, 0 Adc.
3. Vrms = continuous voltage.
4. Vinst = instantaneous voltage at startup.
5. Ambient operating temperature range −40°C to +85°C.
6. Electrical specifications at 25°C.
