CCFL Transformer For Texas Instruments
TPS68000 CCFL Controller
The FA2786-BL was developed specifically for the Texas In-
struments TPS68000 Phase Shift Full Bridge CCFL Controller.
It is designed for use in cold cathode fluorescent 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 driving
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.
