一,产品概述(General Description)         I8S嘉泰姆
      The CXSD61034 is high efficiency synchronous, dual PWM step-down DC/DC converters working under an input voltage range of 2.5V to 5.5V. This feature makes the CXSD61034 suitable for single Li-Lon battery-powered applications. 100% duty cycle capability extends battery life in portable devices, while the quiescent current is 200 A withI8S嘉泰姆
no load, and drops to < 1 A in shutdown.I8S嘉泰姆
    The internal synchronous switch is desired to increase efficiency without an external Schottky diode. The 1.4 MHz fixed switching frequency allows the using of tiny, low profile inductors and ceramic capacitors, which minimized overall solution footprint.I8S嘉泰姆
     The  CXSD61034 converters are available in the industry standard DFN3*3-10L power packages(or upon request).I8S嘉泰姆
