一,产品概述(General Description)      

     The CXSD6144C is a high efficiency current-mode synchronous, 20V/2A buck hgx嘉泰姆

converter. Its input voltage ranges from 4.5V to 20V and it provides an hgx嘉泰姆

adjustable regulated output voltage from 0.923V to 17V while delivering uphgx嘉泰姆

to 2A of output current.hgx嘉泰姆

    The internal synchronous switches increase efficiency and eliminate the need hgx嘉泰姆

for an external Schottky diode. The switching frequency is set to 350KHz.hgx嘉泰姆

 CXSD6144C consists of many protection block such as UVLO, thermal hgx嘉泰姆

protection and output short circuit protection.hgx嘉泰姆

   The CXSD6144C is available in the SOP8 and ESOP8 (with exposed pad hgx嘉泰姆

for heat dissipation) packagehgx嘉泰姆
