Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-1755; Rev 1; 3/01 Wide Brightness Range CCFL Backlight Controllers General.

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.
