一,产品概述(General Description)      

      The CXSD6140 is a high efficiency current-mode asynchronous, 24V/1.2A buck converter.vSd嘉泰姆

Its input voltage ranges from 4V to 24V and it provides an adjustable regulatedvSd嘉泰姆

 output voltage from 0.810V to 5.5V while delivering up to 1.2A of output current.vSd嘉泰姆

     The switching frequency is set to 1.4MHz, which works with a inductor as smallvSd嘉泰姆

as 4.7uH.And the CXSD6140 will automatically switch between PFM and PWM modevSd嘉泰姆

 based on the load current,thus to enhance the converter efficiency at light load.vSd嘉泰姆

      CXSD6140 consists of many protection blocks such as UVLO, input voltage over vSd嘉泰姆

voltage protection to stand much higher input voltage spike, thermal protection andvSd嘉泰姆

 output short circuit protection.vSd嘉泰姆

    The CXSD6140 is available in the tiny SOT23-6 package.vSd嘉泰姆
