The device has a built in power good function to indicate whether the output voltage is regulated properly. As soon as the average inductor current gets limited to a value below the current the voltage regulator demands for maintaining the output voltage the power good output gets low impedance. The output is open drain, so its logic function can be adjusted to any voltage level the connected logic is using, by connecting a pull up resistor to the supply voltage of the logic. By monitoring the status of the current control loop, the power good output provides the earliest indication possible for an output voltage break down and leaves the connected application a maximum time to safely react.
