MAX8709B Datasheet | Maxim Integrated

High-Efficiency CCFL Backlight Controller with SMBus Interface General Description The MAX8709B integrated backlight controller is optimized to drive cold-cathode fluorescent lamps (CCFLs) using a resonant full-bridge inverter architecture. The resonant operation maximizes striking capability and provides near-sinusoidal waveforms over the entire input range to improve CCFL lifetime. The controller operates over a wide input voltage range of 4.6V to 28V with high power-to-light efficiency. The device also includes safetyFeatures that effectively protect against many single-pointfault conditions including lamp-out and short-circuit faults. The MAX8709B achieves 10:1 dimming...
