一,产品概述(General Description)      

   The CXSD6106 is high efficiency synchronous,PWM step-down DC/DC

 converters working under an input voltage range from 2.2V to 5.5V.
This feature makes the CXSD6106 suitable for single Li-Lon battery-powered applications. 100%duty cycle capability extends battery life in portable
devices, while the quiescent current is200μA with no load, and drops
to<1μA in shutdown.
     The internal synchronous switch is desired to increase efficiency without
an external Schottky diode. The 1.0/1.4MHz switching frequency 
allows the using of tiny, low profile inductors and ceramic capacitors,
which minimized overall solution footprint.
    The CXSD6106 converters are available in the industry standard
SOT-23-5L power packages (or upon request).
