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 CXSU63112F is a dual highefficiency PWM step-down DC-DC converter. It is capable of delivering 1A output each channel over a wide input voltage from 2.5V to 5.5V, the CXSU63112F is ideally suited for portable electronic devices that are powered from 1-cell Li-ion battery or from other power sources within the range such as cellular phones, PDAs and other handheld devices. The switching ripple is easily smoothed-out by small package filtering elements due to a fixed operation frequency of 1.5MHz. This along with small DFN-12L 3X3 package provides small PCB area application. Other features include soft start, lower internal reference voltage with 2% accuracy, over temperature protection, and over current protection. 二.产品特点 • 1A Output Current • High Efficiency up to 95% • 2.5V to 5.5V Input Range • Low Quiescent Current CXSU63112 130uA CXSU63112F 20uA CXSU63112F support PFM mode • Adjustable Output from 0.6V to VIN • No Schottky Diode Required • 1.5MHz Constant Frequency Operation • Low Dropout Operation: 100% Duty Cycle • Small 12-Lead DFN Package • RoHS Compliant and 100% Lead(Pb)- Free 三.应用范围 • Personal Information Appliances • Mobile Phones • Wireless and DSL Modems • Portable Instruments 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
