一,产品概述(General Description)      o1x嘉泰姆
o1x嘉泰姆
   The CXSD6106 is high efficiency synchronous,PWM step-down DC/DCo1x嘉泰姆

 converters working under an input voltage range from 2.2V to 5.5V.o1x嘉泰姆
This feature makes the CXSD6106 suitable for single Li-Lon battery-powered applications. 100%duty cycle capability extends battery life in portableo1x嘉泰姆
devices, while the quiescent current is200μA with no load, and dropso1x嘉泰姆
to<1μA in shutdown.o1x嘉泰姆
     The internal synchronous switch is desired to increase efficiency withouto1x嘉泰姆
an external Schottky diode. The 1.0/1.4MHz switching frequency o1x嘉泰姆
allows the using of tiny, low profile inductors and ceramic capacitors,o1x嘉泰姆
which minimized overall solution footprint.o1x嘉泰姆
    The CXSD6106 converters are available in the industry standardo1x嘉泰姆
SOT-23-5L power packages (or upon request).o1x嘉泰姆
