Low-Cost, SMBus, CCFL Backlight Controller

General Description The MAX8759 integrated cold-cathode fluorescent lamp (CCFL) inverter controller is designed to drive CCFLs using a full-bridge resonant inverter. The resonant operation ensures reliable striking and provides near-sinusoidal waveforms over the entire input range. The controll

低成本SMBus CCFL背光控制器

MAX8759集成冷阴极荧光灯(CCFL)逆变控制器采用全桥谐振逆变器设计。在整个输入范围内，谐振工作能够保证可靠启辉，并提供近似正弦的驱动波形。控制器工作在4.5V至28V宽输入电压范围内，具有较高的电能-光能转换效率。器件还具有安全特性，在灯移除、次级过压和次级短路等单点故障情况下能够提供有效保护。\n MAX8759提供精密的灯电流调节(±2.5%)，可实现卓越的CCFL逆变器性能。通过外部电阻调整灯电流；采用数字脉冲宽度调制(DPWM)方法打开/关闭CCFL，可以获得10:1的亮度调节范围，同时保持灯电流不变。MAX8759提供3种机制来控制亮度：2线SMBus™兼容接口、外部 \n• 采用SMBus、PWM接口或者环境光线传感器实现精确的亮度控制 \n• 10:1亮度调节范围，256级分辨率 \n• 谐振工作模式 \n• 近似正弦的灯电流波形，灯寿命更长 \n• 可靠启辉 \n• 较高的电能-光能转换效率 \n• 宽输入电压范围(4.5V至28V) \n• 输入前馈，实现出色的电源抑制 \n• ±2.5%灯电流调节精度 \n• 可调DPWM频率，精度为1.5% \n• 双路灯电流反馈输入 \n• 全面的故障保护 \n• 次级电压限制 \n• 初级电流限制，采用无损耗检测 \n• 灯移除保护，带有可调超时 \n• 次级短路保护 \n• 小型、28引脚、;
