一,产品概述(General Description)      Cwf嘉泰姆

          The CXLE8838 is a high-efficiency buck  constant-current LED driver,designed for driving single or multiple series connected LED efficiently. The device operates from an input supply between 0V and 5.5V and provides an  externally adjustable output current of up to 700mA. Depending upon the supply voltage and external components, the CXLE8838 can drive 3 watts of LED.Cwf嘉泰姆
         The CXLE8838 includes the power switch which operating frequency up to 1.4MHz.       Cwf嘉泰姆

         The CXLE8838 package.is available in SOT-23-5LCwf嘉泰姆
