Cxle87101 is a DC/DC converter designed for the camera module of mobile phone or the high-power LED flash used on the handheld digital camera Its built-in boost DC/DC conversion circuit

The cxle87101 has separate flash mode and movie / torch mode enablers, providing maximum flexibility for different applications. Flash mode has a hard delay of 700ms to produce extremely bright flash. The LED current in flash mode and movie / torch mode is set separately through the external set resistor, which makes the flash solution simple and easy. If both enablers are set to logic high at the same time, the LED current is supplied according to the setting current of the video / torch mode

   产品概述 返回TOPmJ4嘉泰姆


CXLE87101是为手机摄像头模块或手持数码相机上使用 的大功率LED闪光灯而设计的DC/DC转换器。其内置 升压DC/DC转换电路具有高达2MHz的开关频率,可 以为便携设备提供极小整体的闪光灯解决方案。 CXLE87101具有单独的闪光(Flash)模式和摄像/手电筒 (Movie/Torch)模式使能脚,可以为不同应用提供最 大程度的灵活性。Flash模式拥有700ms的硬延迟来产 生极高亮度的闪光。闪光(Flash)模式和摄像/手电 筒(Movie/Torch)模式下的LED电流通过外部的设置 电阻分别设定,这使得闪光灯解决方案简单易行。如 果两个使能脚同时置为逻辑高,LED电流按摄像/手电 筒(Movie/Torch)模式的设置电流来供应。 两路LED输出可以在外围短路以提供更高功率的单 颗LED闪光灯应用,最大可支持1.5A供应电流。内置 热调节功能在闪光(Flash)模式下可以限制IC的壳温 并且可以持续提供允许通过的最大电流。 ACXLE87101置了各种保护特性,包括逐周期的输入限流 保护,输出过压保护,LED失效(开短路)保护和热 关断保护。关断时的电流为0.1uA。 ACXLE87101用TDFN-3×2-14L封装。工作温度范围是 -40 ~ +85 ℃ ℃。mJ4嘉泰姆
