一,产品概述(General Description) 
The CXSD6108 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 CXSD6108 suitable for single Li-Lon battery-powered applications. 100% duty cycle capability extends battery life in portable
devices, while the quiescent current is 200μA with no load, and drops to<1μA
in shutdown.
The internal synchronous switch is desired to increase efficiency without an external Schottky diode. The 1.0MHz/1.4MHz switching frequency allows the
using of tiny, low profile inductors and ceramic capacitors, which minimized
overall solution footprint.
The CXSD6108 converters are available in the industry standard TSOT/
SOT-23-5L power packages (or upon request)
