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 CXSU63107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2A的电流。它的工作电流只有130uA，而当它关机时只消耗1uA。该器件对于诸如手机，手持设备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2A输出的电源。高达1.5MHz的频率可以使外围电路尺寸很小。 CXSU63107具有从0.6V到Vin的宽范围电压输出能力。这个产品的封装是很小的DFN3X3-10L。 The CXSU63107/CXSU63107F synchronous buck converter is a high frequency step-down voltage regulator with current control mode. It can output continuous 2A 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 board level power supply application. This device integrates PWM controller, power switch and compensation network, required only three components to implement a switching power supply. It has internal fixed 1.5MHz frequency and makes application circuit smaller. The CXSU63107/CXSU63107F is available in fixed output voltage version, 1.2V, 1.8V, 3.3V, and is also available in an adjustable output voltage version. The adjustable version has wide output range from 0.6V to VIN. The CXSU63107/CXSU63107F products are available in a SOP8-PP package. 二.产品特点 ● 2.5V 到 5.5V 的输入范围 ● 高达2A的输出电流能力 ● 效率高达95% ● 130uA的低静态耗电流 ● 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 ● 欠压锁定，过流保护，短路保护，热保护 ● 工作温度：-40℃～85℃ ● DFN3*3-10L封装 ● 无铅封装，符合ROHS要求 • 2.5V to 5.5V Input Range • 2A Output Capability • High Efficiency up to 95% • Low Quiescent Current 130uA • 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: -40o C to +85°C • Available in very tiny DFN3X3-10L Package • RoHS Compliant and 100% Lead(Pb)- Free 三.应用范围 ● 手持设备 ● MP3、MP4 ● DSP核供电 ● 板上电源 • 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
