一.产品概述5LY嘉泰姆


    CXSD6229是一颗耐压高至42V,输出电流0.6A的异步降压转换器.。CXSD6229是专为智能电表的供电需求特别优化设计。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,对载波通讯的及内部工作模块影响最小。为了防止电力线波动,CXSD6229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。5LY嘉泰姆

    The CXSD6229 is a wide input range, high-efficiency, and high frequency DC-to-DC step-down switching regulator, capable of delivering up to 1A of output current. With a fixed switching frequency of 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.CXSD6229 also 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 typically between 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, witheven higher transient voltages. With these high input voltages, linear regulators cannot be used for high supply currents without overheating the regulator. Instead, high efficiency switching regulators such as CXSD6229 must be used to minimize thermal dissipation. CXSD6229 is available SOT23-6 Packages. 5LY嘉泰姆
