一,产品概述(General Description)      fIt嘉泰姆
fIt嘉泰姆
   The CXSD6110A CXSD6110 is a high efficiency synchronous,buck DC/DC converter using a
constant frequency, current mode architecture. 100% duty cycle capability extendsfIt嘉泰姆
battery life in portable devices, while the supply current is 200μA with no load, andfIt嘉泰姆
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-IonSwitchingfIt嘉泰姆
frequency is internally set at 0.95MHz,allowing the use of small surface mount inductorsfIt嘉泰姆
and capacitors.The internal synchronous switch increases efficiency and eliminatesfIt嘉泰姆
the need for an external Schottky diode. Low output voltages are easily supportedfIt嘉泰姆
with the 0.8V feedback reference voltage. The CXSD6110A CXSD6110 is available in a low profile  SOT-23-5L package.fIt嘉泰姆
