Two-Channel, Push-Pull CCFL Controller
General Description
The DS3992 is a low-cost, two-channel controller for
cold-cathode fluorescent lamps (CCFLs) that are used
to backlight liquid crystal displays (LCDs). The DS3992
can drive multiple CCFLs per channel, making it ideal
for 4- and 6-lamp LCD PC monitor and TV applications.
The DS3992 uses a push-pull drive scheme to convert a
DC voltage (5V to 24V) to the high voltage (300V RMS to
1400V RMS ) AC waveform that is required to power the
CCFLs. The push-pull drive scheme uses a minimal
number of external components, which reduces compo-
nent and assembly cost and makes the printed circuit
board (PC board) design easy to implement. The push-
pull drive scheme also provides an efficient DC-to-AC
conversion and produces near-sinusoidal waveforms.
