For Texas Instruments  
CCFL Transformer 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.  
Weight 6.0 g  
Terminations Tin-silver (96.5/3.5) over tin over nickel over phos-bronze  
Packaging 400/13reel Plastic tape: 44 mm wide, 0.37 mm thick,  
20 mm pocket spacing, 7.8 mm pocket depth  
PCB washing Tested with pure water or alcohol only. For other solvents,  
see Doc787_PCB_Washing.pdf.
