一,产品概述(General Description) 
The CXSD6110A CXSD6110 is a high efficiency synchronous,buck DC/DC converter using a
constant frequency, current mode architecture. 100% duty cycle capability extends
battery life in portable devices, while the supply current is 200μA with no load, and
drops to<1μA in shutdown. The 2.5V to 5.5V input voltage range makes theCXSD6110A CXSD6110 ideally suited for battery-powered applications.single Li-IonSwitching
frequency is internally set at 0.95MHz,allowing the use of small surface mount inductors
and capacitors.The internal synchronous switch increases efficiency and eliminates
the need for an external Schottky diode. Low output voltages are easily supported
with the 0.8V feedback reference voltage. The CXSD6110A CXSD6110 is available in a low profile SOT-23-5L package.
