  CXSD6226是一款工作电压最高支持36V输入，最大输出电流高达3A的异步降压稳压器。支持0.5A-4A限流点调整，100k-2MHz开关频率可调，芯片过温输出自动智能降额，输出线补可调，支持38V-50V输入OVP，封装简易，采用通用的ESOP-8封装形式，可应用于智能集中器，车载Car-Fi，车载充电器，DCS等中高压大电流市场。

        The CXSD6226 is atotal solutionIC specifically for high voltage USB charging applications. It includes a wide input range, highefficiency, and high frequency DC-to-DC step-down switching regulatorthat is capable of delivering up to 3.1Aof output current. The DC-DC in CXSD6226 is a current mode converter with a fixedfrequency that is externally adjustable. There is also a cable resistance compensation feature that allows users to adjust the output voltage to compensate for the voltage drop due to cable resistance. 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 power-meters as well as automotive applications. In automotive systems, power comes from the battery, with its voltage typicallyranges between 9Vand 24V. Including cold crank and double battery jump-starts, the minimum input voltage may be as low as 4V and the maximum up to 36V, This makes CXSD6226 ideal for the automotive application. CXSD6226 is housed in an ESOP8 package.
