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 (300VRMS to 1400VRMS) AC waveform that is required to power the CCFLs. The push-pull drive scheme uses a minimal number of external components, which reduces component and assembly cost and makes the printed circuit board (PC board) design easy to implement. The pushpull drive scheme also provides an efficient DC-to-AC conversion and produces near-sinusoidal waveforms. |
