Hello,
I have discovered a schematic containing an excellent CCFL Driver IC.
It drives the CCFL direct from the 400V PFC Bus via a half-bridge (pulse transformers to drive both fets).
it is also dimmable.
(There is no need to pre-convert to a low voltage first)
The chip is called BD9247F-HVE2
It has 18 pins.
i can find nothing for it on google, but have seen them on PCB's.
...so someone somewhere has made them.
possible candidate manufacturers are.....................
Sanken
Fuji
Rohm
Toshiba
Maybe others also...
any help in tracking down the datasheet for this device much appreciated.
