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 CXSU63100是一款具有固定工作频率并且内置PFM功能的电流模式控制的的同步降压转换芯片。该芯片轻载时候进入PFM工作模式，此时工作电流只有130uA，而当它关机时只消耗1uA。 CXSU63100具有极低的纹波（＜10mV，测试条件：5V输入，1.8V 1.2A输出，2.2uH 10uF）；极好的负载调整率。 这个器件具有内置的开关，因此不需要外部的续流二极管，另外还具有1.5MHZ的频率可以使外部的pcb的布局面积很小。CXSU63100具有从0.6到Vin的宽范围电压输出能力。这个产品的封装是很小的SOT23-5L The CXSU63100 is a current mode synchronous step-down converter with fixed operating frequency. The supply current is only 130uA 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 circuit smaller. It can reach very ripple with small capacity & inductor. The CXSU63100 is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63100 series products are available in a low profile (1mm) tiny SOT23-5 package. 二.产品特点 ● 1.2A的输出能力 ● 130uA的静态电流 ● 高达96%的效率 ● 2.5V 到 5.5V 的输入范围 ● 0.6V到Vin的可调输出范围 ● 无需外部肖特基二极管 ● 1.5MHz 固定工作频率 ● 电流模式控制 ● 工作温度：-40℃～85℃ ● SOT23-5L的封装 • 1.2A Output Current • High Efficiency up to 96% • 2.5V to 5.5V Input Range • Adjustable Output Voltage from 0.6V to VIN • Low Quiescent Current 130uA • 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: -40o C to +85°C • Available in tiny SOT23-5 Package 三.应用范围 ● DVR ● 通信 ● 工控 ● FPGA ● 行业应用 • 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......
