产品概述 返回TOP
CXLE88129是一款适用于相机模组Flash LED的电荷泵驱动芯片。相比采用电感升压的方式，CXLE88129驱动方案只需一个充电电容，并具有更好的EMI性能。它可工作在闪光灯和手电筒两种工作模式下。在闪光灯模式下最大能输出1A电流，并内置了安全保护时间，以防止LED过热烧毁。CXLE88129采用TDFN-10和WCSP-12的封装。The CXLE88129 is a large-current charge pump designed specifically for white LEDs used in camera flash applications. Only one small bucket capacitor is required to develop the output drive, providing a low EMI solution compared with inductive boost regulators. The CXLE88129 has two operation modes: Flash mode and Movie mode. In Flash mode, the CXLE88129 is capable of delivering up to 1A. A safety timer is also included to ensure the LED can not be on indefinitely and overheat. The CXLE88129 is available in a 10-pin TDFN and WCSP-12 packages.
