高效率、宽亮度范围、CCFL背光控制器

MAX1895/MAX1995集成控制器采用同步全桥逆变器结构，用于驱动冷阴极荧光灯管(CCFL)。同步驱动结构在整个输入范围内提供近似正弦的驱动波形，最大限度地延长了CCFL的寿命。MAX1895/MAX1995工作在较宽的输入电压范围，具有较高的效率和更宽的亮度调节范围。\n MAX1895/MAX1995的安全功能包括：限制变压器次级线圈的电压、提供灯管损坏和短路故障等单点故障保护。\n MAX1895/MAX1995可以采用三种方式调节CCFL的亮度：线性控制灯管电流，数字脉宽调制(DPWM)调节灯管电流或同时采用两种方法以获得最宽的亮度调节范围(大于30:1)。CCFL的亮度可以通过 \n• 同步谐振频率 \n• 优异的振幅因子延长灯管寿命 \n• 保证最强的开启能力 \n• 高发光效率 \n• 宽亮度调节范围(3种调节方式) \n• 灯管电流调节：大于3:1 \n• 数字PWM (DPWM)：大于10:1 \n• 综合调节：大于30:1 \n• 输入电压前馈补偿 \n• 宽输入电压范围(4.6V至28V) \n• 限制变压器次级线圈电压以减小变压器的压力 \n• 2秒超时灯管损坏保护 \n• 短路及其他单点故障保护 \n• 可同步DPWM频率 \n• 双模亮度控制接口 \n• SMBus串行接口(仅MAX1895) \n• 模拟接口(MAX1895/MAX1995) \n;
