一.产品概述TmZ嘉泰姆

   CXSD6225是一颗耐压高至42V，输出电流1.5A的异步降压转换器.。CXSD6225是专为车载设备的需求特别优化设计。其采用特别的PWM控制技术，在实现上述要求的同时保持输出纹波最小，对行车记录仪的摄像模组，车载音响设备影响最小。为了防止汽车电源的波，CXSD6225增加了输入过压保护，当输入电压大于38V后，把输出关掉，保护后端用电设备。 TmZ嘉泰姆

  The CXSD6225 is a wide input range, high-efficiency, and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 1.5A of output current. With a fixed switching frequencyof 650KHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors.CXSD6225also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. An OVP function protects the IC itself and its downstream system against input voltage surges. With this OVP function, the IC can stand off input voltage as high as 42V, making it an ideal solution for industrial applications such as smart meters as well as automotive applications. In automotive systems, power comes from the battery, with its voltage typicallybetween 9Vand 24V. Including cold crank and double battery jump-starts, the minimum input voltage may be as low as 4Vand the maximum up to 36V, with even higher transient voltages. With these high input voltages, linear regulators cannotbe used for high supply currents withoutoverheating the regulator. Instead, high efficiencyswitching regulators such as CXSD6225 must be used to minimize thermal dissipation. CXSD6225 is available SOT23-6 Packages TmZ嘉泰姆
