TPS6213X系列是一款简单易用的同步降压DC-DC转换器,针对高功率密度的应用进行了优化。该器件的开关频率典型值高达2.5MHz,允许使用小型电感,利用DCS-Control™拓扑技术提供快速瞬态响应并实现高输出电压精度。
该器件的宽运行电压范围为3V至17V,非常适用于由锂离子或其他电池以及12V中间电源轨供电的系统。它在输出电压介于0.9V至6V之间时支持高达3A的持续输出电流(使用100%占空比模式)。输出电压启动斜坡由软启动引脚控制,从而允许作为独立电源或者在跟踪配置下的运行。通过配置使能和开漏电源正常引脚也有可能实现电源排序。
在节能模式下,该器件在输入电压V IN 作用下生成约17μA的静态电流。如果负载小,则自动且无缝进入省电模式,在全部负载范围内保持高效率。在关断模下,此器件被关闭且关断流耗少于2μA。
此器件分为可调和固定输出电压型号,采用3mm×3mm(RGT)16引脚超薄四方扁平无引线( VQFN)封装。
