CCFL背光灯及LCD对比度控制负压控制器

MAX753/MAX754驱动冷阴极荧光灯(CCFL)并为彩色或单色LCD面板提供LCD背板偏置（对比度）电源。这些IC专为背光笔记本电脑应用而设计。\n\n 背板偏置和CCFL电源均可独立关断。当两个部分都关断时，电源电流降至25µA。LCD对比度和CCFL亮度可通过为单独的数字输入提供时钟或使用外部电位器来调节。在关断时，LCD对比度和背光亮度设置保存在各自的计数器中。上电时，LCD对比度计数器和CCFL亮度计数器设置为半量程。\n\n 这些IC由5V稳压电源供电。磁性元件直接连接到电池，以充分提高电源效率。\n\n CCFL驱动器采用Royer型谐振架构。它 • 驱动背板和背光\n\n• 电池电压范围：4V至30V\n\n• 电源电流低至500µA\n\n• 以数字方式或通过电位器控制CCFL亮度和LCD偏置电压\n\n• 负LCD对比度(MAX753)\n\n• 正LCD对比度(MAX754)\n\n• 独立关断背光和背板部分\n\n• 关断电流：25µA;
