     CXLE88131是一款4MHz固定工作频率电流模式同步升压转换器。它能为LED闪光灯提供1.5A恒定电流驱动。CXLE88131内置I2C总线接口，通过I2C控制接口可以实现对CXLE88131的开启和关断，并能设置其电流大小。CXLE88131通过两个逻辑输入端STROBE和TX/TORCH能在大电流情况下中断闪光灯模式。在闪光灯模式下，LED电流可以设定为从93.75mA到1.5A的16种电流值；而在手电筒模式下，LED电流大小可以设定为从48.4mA到375mA。在LED开路的情况下，CXLE88131能通过过压保护电路使得输出电压低于过压保护阈值电压；同时在输出短路到地的情况下，短路保护电路能起到保护作用。CXLE88131采用9球的WCSP封装，封装尺寸为1.61毫米×1.61毫米。The CXLE88131 is a 4MHz fixed frequency, current mode synchronous boost converter. The device is designed to operate 1.5A constant current driver for flash white LED applications. An industry-standard I2C serial digital input is used to enable, disable and set the current for flash LED. The CXLE88131 has two logic inputs including a hardware Flash Enable (STROBE) and a Flash Interrupt input (TX/TORCH) designed to interrupt the flash pulse during high battery current conditions. In flash mode, the LED current source provides 16 target current levels from 93.75mA to 1.5A. And also tin torch mode, the programmable current ranges from 48.4mA to 375mA. An over voltage protection feature keeps the output voltage below the OVP threshold in the case of an open LED and an output short circuit protection limits the output current during an output short to GND. CXLE88131is available in a small 9-bump (1.61mm ×1.61mm) WSCP package.
