19-1755; Rev 1; 3/01 Wide Brightness Range CCFL Backlight Controllers General Description The MAX1739/MAX1839 fully integrated controllers are optimized to drive cold-cathode fluorescent lamps (CCFLs) using the industry-proven Royer oscillator inverter architecture. The Royer architecture provides near sinusoidal drive waveforms over the entire input range to maximize the life of CCFLs. The MAX1739/ MAX1839 optimize this architecture to work over a wide input voltage range, achieve high efficiency, and maximize the dimming range. The MAX1739/MAX1839 monitor and limit the transformer center-tap voltage when required. This ensures minimal voltage stress on the transformer, which increases the operating life of the transformer and eases its design requirements.
