Cxle8703 is a control chip specially designed for LED flashlight miner's lamp, headlight supports a set of LED lights and the control of the lights is completed by the switch

Cxle8703 is a control chip specially designed for LED flashlight, miner's lamp, headlight, etc. Cxle8703 supports a set of LED lights, and the control of the lights is completed by the switch. Cxle8703 has two working modes: in working mode 1, the LED light can be switched between "full on" and "flashing"; in working mode 2, the LED light can be switched from "full on" to "dim on" of 1 / 4 brightness and then to "flashing" state, and the three working states are switched back and forth. Le8703 maximum working current is 200mA

一.产品概述qDL嘉泰姆


  CXLE8703是一款专门为LED手电筒、矿灯、头灯等设计的控制芯片。qDL嘉泰姆
  CXLE8703支持一组LED灯,灯的控制由开关来完成。CXLE8703有两种工作模式:
qDL嘉泰姆

在工作模式1下,LED灯可在“全亮”和“闪亮”这两种工作状态之间切换;qDL嘉泰姆

在工作模式2下,LED灯可从“全亮”状态切换到1/4亮度的“暗亮”状态再到“闪亮”状态,这qDL嘉泰姆

三种工作状态是循环往复切换的。qDL嘉泰姆
  CXLE8703最大工作电流为200mA。qDL嘉泰姆
  CXLE8703采用SOT23、SOT23-5和TO92等三种封装。
