一,产品概述(General Description)      3n6嘉泰姆
3n6嘉泰姆
   The CXSD6109 is a high efficiency synchronous,dual channel PWM step-down3n6嘉泰姆
DC/DC converter working under an input voltage range from 2.5V to 5.5V. It3n6嘉泰姆
integrates two PWM synchronous step-down DC-DC converters. 100% duty cycle3n6嘉泰姆
capability extends battery life in portable devices,while the quiescent current (one3n6嘉泰姆
channel) is 200μA with no load, and drops to<1μA in shutdown.Each DC-DC3n6嘉泰姆
converter has independent enable input and short-circuit protection allowing 3n6嘉泰姆
versatile power sequence combination. The CXSD6109 converters are available3n6嘉泰姆
in the industry standard DFN3*3-10L packages (or upon request).3n6嘉泰姆
