一,产品概述(General Description)      TNO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 withTNO嘉泰姆
no load, and drops to < 1 A in shutdown.TNO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.TNO嘉泰姆
     The  CXSD61034 converters are available in the industry standard DFN3*3-10L power packages(or upon request).TNO嘉泰姆
