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 CXSD6222是一款在SOT23-8的超小封装内实现工作电压达18V，输出电流达2A，能量转换效率达91%的高压同步降压转换器。其采用了PWM/PFM自动切换的轻载高效控制模式和内部补偿的构架。是外围引脚最为节省的高压同步降压转换器 The CXSD6222 is a wide input range, synchronous, high-efficiency, DC-to-DC step-down switching regulator, capable of delivering up to 2A of output current. With a fixed switching frequencyof 500KHz, this current mode PWM controlled converter allows the use of small external components, such as ceramic input and output caps, as well as small inductors.CXSD6222 also employs a proprietary control scheme that switches the device into a power save mode during light load, thereby extending the range of high efficiency operation. What is unique about CXSD6222 is that it is packaged in a tiny space saving SOT23-8 package 二.产品特点 ◆宽输入电压4.2-18V ◆转换效率高达91% ◆耐受输入峰值电压达30V ◆Wide Input Operating Range from 4V to 18V ◆ High Efficiency at 12V In 5V Out: Up to 91%: ◆ High Efficiency PFM mode at light load ◆ Capable of Delivering 2A ◆ No External Schottkyand Compensation Needed ◆ Current Mode control ◆ Logic Control Shutdown ◆ Thermal shutdown and UVLO ◆ Available in SOT23-8 Package 三.应用范围 ◆机顶盒 ◆LCDTV ◆玩具 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
