Its function is to provide a latching switch action upon sensing an inputthresholdvoltage, with reset accomplished by an external clock signal.
它的功能是当感应到输入电压界限时提供一个锁存开关，通过外部时钟信号完成复位。

If the noise level is just below the threshold needed to flip the state of the system, even a tiny inputvoltage is enough to change the system's state.
如果噪音的等级正好比转换系统状态的极限低，一个非常小的输入电压就足以改变系统的状态。

When the switching voltage is at or below 1.5v, connecting an external resistive divider to this input will lower the UVLO threshold.
