一.产品概述z4R嘉泰姆

   CXSU6390是功能，引脚雷同于CXSU6388的一颗5V/2.5A的真关断同步升压稳压器。相比于CXSU6388，CXSU6390允许更大的输出电流。其采用了1MHz的振荡频率，使用2.2uH电感可以实现输出很小的纹波。同时集成了锂电池低电压保护功能，以及USB的D+/D-接口可同时模拟出BC1.2 DCP / 苹果5V 2.4A / 三星平板充电器的充电接口。是非常适合移动电源，平板电脑，MIFI等大容量锂电池系统，需要在USB接口提供2A电流的应用系统中。z4R嘉泰姆

     CXSU6390 is an CX Solutions’ high efficiency, high frequency synchronous Step-Up converter, capable of delivering output current up to 2.5A at a 5V output from input as low as 3.3V. With a low Rdson Power MOS and a built-in synchronous rectifier, its efficiencycan be as high as 93% at a 5V/2.1A load. This greatly minimizes power dissipation and reduces heat on the IC, making it ideal for applications that require smallboard space and have stringent temperature constraints, such as power banks and mobile devices. CXSU6390 also integrates an USB emulator that provides correct electricalsignatureon the D+/D- for charging compliant devices. CXSU6390 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 switchingfrequency, small external input and output capacitors and inductor can be used.z4R嘉泰姆
