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 CXSU63102是一款具有固定工作频率的电流模式控制的同步降压转换芯片，该芯片最高可以输出1.5A的电流。它的工作电流只有130uA，而当它关机时只消耗1uA。该器件对于诸如数据卡，手机等设计空间要求高的电池供电产品来说是一个很好的解决方案。 该产品内部集成了PWM控制器，功率开关管和内部补偿网络，最少只需要5个外围器件就可以实现一个高达1.5A输出的电源。高达1.5MHz的频率可以使外围电路尺寸很小。 The CXSU63102/CXSU63102F synchronous buck converter is a high frequency stepdown voltage regulator with current control mode. It can output 1.5A with excellent line and load regulation. The current is only 130uA/20uA at operating and less than 1uA at shutdown. This device is the ideally solution for small space and battery powered consume application, such as cellular phone and Hand-held device. The CXSU63102/CXSU63102F integrates PWM controller, power switch and compensation network, required only five components to implement a 1.5A output switching power supply. It has internal fixed 1.5MHz frequency and makes application circuit smaller. The CXSU63102/CXSU63102F is available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63102/CXSU63102F series products are available in a DFN-6L 2X2package. 二.产品特点 ● 2.5V 到 5.5V 的输入范围 ● 高达1.5A的输出电流能力 ● 效率高达95% ● CXSU63102 130uA的低静态耗电流 CXSU63102F 20uA的低静态耗电流 CXSU63102F支持PFM模式 ● 1.5MHz的恒定工作频率 ● 0.6V到Vin的可调输出范围 ● 占空比可达100% ● 电流模式控制 ● 工作温度：-40℃～85℃ ● DFN封装 ● 2.5V to 5.5V Input Range ● 1.5A Output Capability ● High Efficiency up to 95% ● Low Quiescent Current CXSU63102 130uA CXSU63102F 20uACXSU63102F support PFM mode ● Adjustable Output Voltage from 0.6V to VIN ● 1.5MHz Constant Frequency Operation ● Low Dropout Operation: 100% Duty Cycle ● Under Voltage Lockout, Over Current, Short Current, and Thermal Protection ● Operating Temperature: -40oC to +85°C ● Available in very tiny DFN2X2 Package ● RoHS Compliant and 100% Lead(Pb)- Free 三.应用范围 ● 数据卡 ● 3G上网卡 ● 手持设备 ● 智能手机 ● 数码相框 ● Handheld Instruments ● MP3/4 Player ● DSP Core Supplies ● Board Mounted Power Supplies 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
