这个器件为电池供电的/永远在线的汽车应用（如遥控免钥匙进入（RKE）或被动进入被动启动（PEPS）钥匙和基站）提供了低功耗优势。借助2V-6V的输入电压范围，这些器件支持由锂二氧化锰（Li-MnO2）纽扣电池，锂离子电池，两节（2S）和三节（3S）碱性电池，3.3V和5V输入电压轨进行供电的应用.TPS6224x-Q1在高负载电流情况下以2.25MHz的固定开关频率运行，在轻负载电流情况下会进入省电模式，以便在整个负载电流范围内保持高效率和低功耗。此省电模式针对低输出电压纹波进行了优化。在关断模式下，电流消耗减少至1μA以下.TPS6224x-Q1允许使用小型电感器和电容器来实现较小的解决方案尺寸，并采用5引脚TSOT23封装。
