一.产品概述6fK嘉泰姆

 CXSU6391是一款输出达5V/3A, 3.3V输入下升压5V/2A效率高达90%以上的真关断同步升压转换器。CXSU6391采用了1MHz的振荡频率，采用2.2uH电感，仅需要一个22uF输出电容即可达到50mV的输出纹波。在如此大电流，高效率，高稳定性输出的条件下，同时具备极高功率密度的设计，采用DFN3x3-12的封装包装形势。特别适合MIFI、Mini PCI-E模块、移动电源、大功率蓝牙音箱等大容量锂电池对外需输出大功率5V电压的电子系统。6fK嘉泰姆

  CXSU6391 is an CX Solutions’ high efficiency, high frequency synchronous Step-Up converter, capable of delivering output current up to 3A at a 5V output from a 3.6V input. With a low Rdson Power MOS and a built-in synchronous rectifier, its efficiencycan be as high as 91% at a 5V/2.1A load. This greatly minimizes power dissipation and reduces heat on the IC, making it ideal for applications that require small board space and have stringent temperature constraints, such as power banks and mobile devices. CXSU6391 also incorporates CX Solutions’ True-Shutoff○R technology that protects against overload and short-circuit conditions. All of these features are integrated in a tiny DFN3x3-12 package. With 1MHz switching frequency, small external input and output capacitors and inductor can be used. 6fK嘉泰姆
