LM2756是一个高度集成的,开关电容,多显示屏LED驱动器,可以驱动多达8个LED,总输出电流180mA的电流并行。 规管的内部电流源提供极好的电流和所有LED的亮度匹配。

被分成三组独立控制的LED驱动电流吸收。 初级组(A组),可配置为驱动四个,五个或六个LED使用的主要手机显示屏,而第二组(B组),可配置到一个,两个或三个LED驱动器用于驱动辅助显示器,键盘和/或LED指示灯。 一个额外的驱动,D1C,提供额外的参考指标照明功能。

该器件提供出色的效率,无电感器的使用,在3 / 2的增益或传递模式电荷泵。 选择适当的维持电流调节增益,基于LED的正向电压,使效率最大化是在输入电压范围。

LM2756是在全国20的微小凸点,0.4mm间距,薄型micro SMD封装。
