If any questions arise on whether to use the “Rated Ambient Temperaute” or the “Rated Terminal Part Temperature” in your usage conditions, please give priority to the “Rated
Terminal Part Temperature.” Prior to use and for more details, refer to “Introduction of the derating curves based on the terminal part temperature” in the beginning of our catalog.
Temperature rise at high power will depend on PCB layout. Be sure to contact factory prior to use and monitor terminal part temperature.
驱车行驶在城市的大街上时,环顾一下四周,您会看到越来越多的全色 LED 标牌及留言板出现在商店、饭店和办公大楼的外墙上。随着 LED 矩阵显示系统产量的快速增长,广告标牌现在可提供商店老板可承受的价格。为了支持这一需求,我们正在努力开发新技术,进一步优化可实现这些显示屏的 LED 驱动器。 今年年初,TI 推出了业界第一个 48 输出(48 通道)LED 标牌显示器驱动器产品系列。TL...[详细]
