MAX8709B - High-Efficiency CCFL Backlight Controller
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 lifet
MAX8709B Features
* that effectively protect against many single-pointfault conditions including lamp-out and short-circuit faults. The MAX8709B achieves 10:1 dimming range by “chop- ping” the lamp current on and off using a digital pulse- width-modulation (DPWM) method. The minimum DPWM duty cycle of the MAX8709B
