在线产品描述:
TLC591X-Q1恒流LED散热驱动器设计 单独工作或级联工作。因为每个输出都是独立控制的，所以它们可以编程 由用户打开或关闭。高LED电压(VLED)允许每个输出使用一个LED 或单个串上的多个LED。具有独立控制的输出，恒定供应 电流，LED可以并联组合，在单串上产生更高的电流。这个 所有通道的恒定吸收电流通过单个外部电阻设置。这使得 不同的LED驱动器在相同的应用中吸收不同的电流，这提供了可选的 多色LED的实施。独立输出的另一个优势是 使未使用的频道保持浮动的能力。TLC591x-Q1 LED驱动器的灵活性非常理想 用于例如(但不限于)：汽车LED照明，7段显示器， 滚动单色显示屏、游戏机、白色家电、视频广告牌和视频 面板。
