安森美半导体推出的8段三色 LED 驱动器 NLSF595可应用于键盘照明以及无线手持设备、数码静止图像照相机、数码摄像机和 MP3播放器的特殊照明等方面。在十分重要的待机状态下,NLSF595的功耗几乎为零。在25℃时,其静态供电电流低于1.0 μA。该器件工作电压范围广(20～50V),并可支持25MHz 以上的数据速率。在3.3V 电压下工作时,数据能以50MHz 速率输入 NLSF595。该驱动器具有输出过压容差,可直接驱动 LED,同时可与高达7V
ON Semiconductor 8-segment tri-color LED driver NLSF595 can be applied to keyboard lighting and wireless handheld devices, digital still cameras, digital video cameras and MP3 players, special lighting and so on. In a very important standby state, NLSF595 power consumption is almost zero. At 25 ° C, the static supply current is less than 1.0 μA. The device operates over a wide voltage range (20 to 50V) and can support data rates above 25MHz. When operating at 3.3V, the data can be input to the NLSF595 at 50MHz. The driver has output overvoltage tolerance, can directly drive the LED, while with up to 7V
