Hi there - I was just looking at a datasheet for some CCFL transformers
What exactly does this mean? Does it mean the secondary is shorted to the primary? Or something else?
Thanks!

Dunno, if there were a connection I think it would be indicated. Maybe it refers to insulation value -- floating is higher pot?

** Email the company and ask them - as they seem to have invented their own term for the design.The "floating" and "fixed" secondary versions vary only in pin out, as far as the specs indicate.

the connection is indicated. For the fixed type one end of the secondary has has same pin number as the center of primary

Hi,
The terminology appears to define how the back-light is wired. In the 'fixed' mode one end of the secondary and the light are connected to a current sense circuit that feeds back to the controlling IC. In the 'floating' mode however, it is connected only to the secondary winding (through a capacitor). It would seem from this that one end of the secondary is at a fixed potential in the first case but the whole of it floats in the other.
