一,产品概述(General Description)      7l2嘉泰姆
7l2嘉泰姆
   The CXSD6108 is high efficiency synchronous,PWM step-down DC/DC converters working under an input voltage range from 2.2V to 5.5V.7l2嘉泰姆
This feature makes the CXSD6108 suitable for single Li-Lon battery-powered applications. 100% duty cycle capability extends battery life in portable7l2嘉泰姆
devices, while the quiescent current is 200μA with no load, and drops to<1μA7l2嘉泰姆
in shutdown.7l2嘉泰姆
   The internal synchronous switch is desired to increase efficiency without an external Schottky diode. The 1.0MHz/1.4MHz switching frequency allows the7l2嘉泰姆
using of tiny, low profile inductors and ceramic capacitors, which minimized7l2嘉泰姆
overall solution footprint.7l2嘉泰姆
  The CXSD6108 converters are available in the industry standard TSOT/7l2嘉泰姆
SOT-23-5L  power packages (or upon request)7l2嘉泰姆
