数据： 采用 6 引脚、0.35mm 间距 WCSP 封装的 TPS6280x 1.8V 至 5.5V、0.6A/1A、2.3µA IQ 降压转换器 数据表 (Rev. B)
TPS6280x器件系列是一款降压转换器，具有2.3μA的典型静态电流以及最高的效率和最小的解决方案尺寸。凭借TI的DCS-Control™拓扑，该器件能够使用微型电感器和电容器工作，并且具有高达4MHz /1.5MHz的开关频率。在轻负载条件下，该器件会无缝进入省电模式，以缩短开关周期并保持高效率。
将VSEL /MODE引脚连接到GND可以选择1.2V的固定输出电压。只需将一个外部电阻器连接到VSEL /MODE引脚，就可选择16种内部设置的输出电压。一个集成R2D（电阻器到数字）转换器可读取外部电阻器并设置输出电压。只需更改单个电阻器，即可将同一个器件部件号用于不同的应用和电压轨。此外，与传统的外部电阻分压器网络相比，内部设置的输出电压可提供更高的精度。该器件启动之后，直流/直流转换器将进行入强制PWM模式（通在该工作模式下，此器件通常以4MHz /1.5MHz的开关频率运行，从而能够实现最低的输出电压纹波.TPS6280x器件系列采用具有0.35mm间距的微型6引脚WCSP封装。
