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 CXSD6118 SwitchReg is a 1.5MHz constant fre-quency current mode PWM step-down converter. It is ideal for portable equipment requiring very high current up to 2A from single-cell Lithium-ion batteries while still achieving over 90% efficiency during peak load condi-tions. The CXSD6118 also can run at 100% duty cycle for low dropout operation, extending battery life in portable systems while light load operation provides very low output ripple for noise sensitive applications.The CXSD6118 can supply up to 2A output load current from a 2.5V to 5.5V input voltage and the output voltage can be regulated as low as 0.6V. The high switching fre-quency minimizes the size of external components while keeping switching losses low. The internal slope compen-sation setting allows the device to operate with smaller inductor values to optimize size and provide efficient operation. The CXSD6118 is available with adjustable (0.6V to VIN) output voltage 二.产品特点 ●Input Voltage Range: 2.5V to 5.5V ●Output Voltages from 0.6V to VIN ●2A Output Current ●High Efficiency: Up to 96% ●1.5MHz Constant Switching Frequency ●Low RDS(ON) Internal Switches: 0.13Ω ●Allows Use of Ceramic Capacitors ●Current Mode Operation for Excellent Line and Load Transient Response ●Short-Circuit and Thermal Fault Protection ●Soft Start ●Low Dropout Operation: 100% Duty Cycle ●Low Shutdown Current: ISHUTDOWN < 1μA ●SOT23-6 Package ●-40°C to +125°C Temperature Range 三.应用范围 ●Cellular Phones ●Digital Cameras ●DSP Core Supplies ●PDAs ●Portable Instruments ●Smart Phones 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
