Two-Channel, Push-Pull CCFL Controller  
DS392  
General Description  
Features  
ꢀ Two-Channel CCFL Controller for Backlighting  
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.  
LCD Panels for PC Monitors and LCD-TVs  
ꢀ Minimal BOM Provides Low-Cost Inverter Solution  
ꢀ Per-Channel Lamp Fault Monitoring for Lamp-  
Open, Lamp Overcurrent, Failure to Strike, and  
Overvoltage Conditions  
The DS3992 uses a push-pull drive scheme to convert a  
ꢀ Accurate (±±10% On-Board Oscillator for Lamp  
DC voltage (5V to 24V) to the high voltage (300V  
to  
RMS  
Frequency (41kHz to 81kHz%  
1400V  
) AC waveform that is required to power the  
RMS  
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.
