The LX6501 is a high performance
CCFL controller optimized for LCD-
TV and other multi-lamp LCD display
applications.
The
controller
integrated on chip gate drivers with
adequate capacity to drive N channel
power MOSFET’s on both low side
and high side of a full bridge inverter
with input voltage of up to 27V. An
on-chip
regulator
internal driver operating voltage to
supply the output gate drive circuit.
This allows a direct connection of the
controller to the inverter supply
minimizing external components.
In addition, it also provides
synchronization capability that allows
the user to synchronize both the
frequency and phase of the lamp
current between inverters or to an
external synchronization signal.

performance is also enhanced to
improve both the regulation accuracy
and the dynamic response at transient
conditions.
In addition a comprehensive dimming
control feature is facilitated to satisfy
various brightness control requirements.
The LX6501 includes extensive fault
detection functions, including open
lamp, over voltage, short circuit, over
current, and over temperature protection.
