采用3mm x 3mm 四方扁平无引线(QFN) 封装的3-17V 1A 降压转换器 数据表 (Rev. A)
TPS6215xx-Q1系列是一款易于使用的同步降压DC-DC转换器,其针对高功率密度应用进行了优化。典型2.5MHz高开关频率允许使用小型电感器并且通过使用DCS-Control™拓扑技术提供快速瞬态响应以及高输出电压精度。
借助其3V至17V宽运行输入电压范围,此器件非常适合用于由锂离子或者其它电池以及由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1A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。
