一,产品概述(General Description)      
直线
   The CXSD6141  CXSD6141B  is a wide input range, high-efficiency,and high frequency DC-to-DCixR嘉泰姆

step-down switching regulator, capable of delivering up to 0.7A of output current. ixR嘉泰姆

With a fixed switching frequency of 660KHz, this current mode PWM controlled ixR嘉泰姆

converter allows the use of small external components, such as ceramic input andixR嘉泰姆

output caps, as well as small inductors.CXSD6141 also employs a proprietary control ixR嘉泰姆

scheme that switches the device into a power save mode during light load, thereby ixR嘉泰姆

extending the range of high efficiency operation. An OVP function protects the ICixR嘉泰姆

itself and its downstream system against input voltage surges. With this OVPixR嘉泰姆

function, the IC can stand off input voltage as high as 42V, making it an idealixR嘉泰姆

solution for industrial applications such as smart meters as well as automotiveixR嘉泰姆

applications.ixR嘉泰姆

  In automotive systems, power comes from the battery, with its voltage typically ixR嘉泰姆

between 9V and 24V. Including cold crank and double battery jump-starts, ixR嘉泰姆

the minimum input voltage may be as low as 4V and the maximum up to 36V, with ixR嘉泰姆

even higher transient voltages. With these high input voltages, linear regulators cannot ixR嘉泰姆

be used for high supply currents without overheating the regulator. Instead, high efficiency ixR嘉泰姆

switching regulators such as CXSD6141 must be used to minimize thermal dissipation.ixR嘉泰姆

  CXSD6141 is available SOT23-6 Packages.ixR嘉泰姆
