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 CXSU6326 is the industry's first 5-lead SOT-23 current mode DC/DC converter. Intended for small, low power applications, it operates from an input voltage as low as 1.1V and switches at 1.4MHz, allowing the use of tiny, low cost capacitors and inductors 2mm or less in height. Its small size and high switching frequency enables the complete DC/DC converter function to take up less than 0.2 square inches of PC board area. Multiple output power supplies can now use a separate regulator for each output voltage, replacing cumbersome quasi-regulated approaches using a single regulator and a custom transformer. A constant frequency, internally compensated current mode PWM architecture results in low, predictable output noise that is easy to filter. The high voltage switch on the CXSU6326 is rated at 36V, making the device ideal for boost converters up to 34V as well as for Single-Ended Primary Inductance Converter (SEPIC) and flyback designs. The device can generate 5V at up to 200mA from a 3.3V supply or 5V at 175mA from four alkaline cells in a SEPIC design. The CXSU6326 is available in the 5-lead SOT-23 package. 二.产品特点 ■ Uses Tiny Capacitors and Inductor ■ Internally Compensated ■ Fixed Frequency 1.4MHz Operation ■ Operates with VIN as Low as 1.1V ■ 3V at 30mA from a Single Cell ■ 5V at 200mA from 3.3V Input ■ 15V at 60mA from Four Alkaline Cells ■ High Output Voltage: Up to 34V ■ Low Shutdown Current:<1m A ■ Low VCESAT Switch: 300mV at 300mA ■ Tiny 5-Lead SOT-23 Package 三.应用范围 ■ Digital Cameras ■ Pagers ■ Cordless Phones ■ Battery Backup ■ LCD Bias ■ Medical Diagnostic Equipment ■ Local 5V or 12V Supply ■ External Modems ■ PC Cards 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
