一.产品概述
CXSU6388是一款输出达5V/2.5A, 3.3V输入下升压5V/2A效率高达90%的真关断同步升压转换器。CXSU6388采用了1MHz的振荡频率，采用2.2uH电感，仅需要两个22uF输出电容即可达到50mV的输出纹波。同时CXSU6388集成了能兼容苹果和三星平板电脑大电流充电的USB接口自动识别功能。极大简化了整机产品的设计。CXSU6388采用DFN3x3-12封装，特别适合移动电源、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。
CXSU6388 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 heaton the IC, making it ideal for applications that require smallboard space and have stringent temperature constraints, such as power banks and mobile devices. CXSU6388 also integrates an USB emulator that provides correct electricalsignatureon the D+/D- for charging compliant devices. CXSU6388 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.
