目录 1.产品概述 2.产品特点 3.应用范围 4.技术规格书下载（PDF文档） 一.产品概述 The CXSU63115 is a current mode synchronous step-down converter with fixed operating frequency and integrating PFM mode function. In light load condition,PFM function can increase the system efficiency and enhances the life of system power supply. The supply current is only 20uA at operating and less than 1uA at shutdown. This device is the ideally solution for Li-Ion battery powered system applications and small size board applications. This device has internal switch, no external diode. It has internal fixed 1.5MHz frequency and makes application circuitsmaller. The CXSU63115 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63115 series products are available in a low profile (1mm) tiny SOT23-5 package. 二.产品特点 • 1.2A Output Current • High Efficiency up to 96% • 2.5V to 5.5 V Input Range • Adjustable Output Voltage from 0.6V to VIN • Low Quiescent Current 20uA • No Schottky Diode Required • 1.5MHz Constant Frequency Operation • Low Dropout Operation: 100% Duty Cycle • Current Mode Operation for Excellent Line and Load Transient Response • Operating Temperature: -40oC to +85°C • Available in tiny SOT23-5 Package 三.应用范围 • Mobile Phone/Smartphone • DVB • GPS • FPGA Core Power Supply • Communications 四.技术规格书（产品PDF) 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 五.产品封装图 六.电路原理图 七.相关芯片选择指南 更多同类产品......
