LM3535是一个高度集成的LED驱动器能够驱动8个LED大屏幕显示应用并行。 独立的LED控制允许的6个主要的局部照明应用选择的LED显示的一个子集。 另外的6个主要银行,LM3535是一个额外的2个独立控制的LED驾驶支持指标应用能力。

The LED driver current is absorbed into three groups of independently controlled LEDs. 可配置的主组,以驱动多达6个主要手机显示屏使用LED。 B,C组提供驾驶辅助显示器,键盘和LED指示灯。 所有的LED电流源,可以独立提供灵活性,以解决不同的应用需求开启和关闭。

LM3535提供多区域环境光传感(1或2 ALS的输入选项取决于),允许自主控制背光强度在不断变化的环境光线条件下的事件。 PWM输入,还提供给用户的一种手段,根据显示的内容后动态调整背光强度。

LM3535提供出色的效率,无电感器的使用,在3 / 2的增益或传递模式电荷泵。 Choosing the appropriate maintenance current regulation gain, based on the LED's forward voltage, maximizes efficiency over the input voltage range.

LM3535是在全国20的微小凸点,0.4mm间距,薄型micro SMD封装。
