The NCV8170AXV180T2G working principle refers to the principle where an input voltage is converted to a regulated output voltage, by using a control circuit. This control circuit transforms the input voltage to achieve the desired output voltage. It is based on the voltage divider principle, in which two resistors of different values are connected in series with a voltage source. The ratio of the two resistors decides the division of the output voltage. Depending on the application, the value of these two resistors can be selected, in order to generate the required output voltage. The components in this control circuit that work together also affect its working principle. This includes a Zener diode, which protects the system against any overload of voltage. The control circuit also contains MOSFET (Metal Oxide Semiconductor Field Effect Transistor), which helps to maintain a constant output voltage, despite the fluctuation of the input voltage. It also has a comparator, which can compare the output voltage with a reference voltage and enable the system to pass only the desired output voltage.

In conclusion, the NCV8170AXV180T2G is a linear voltage regulator that belongs to PMIC family and is widely used across many application fields. It works on the principle of the voltage divider, in which the ratio of two resistors in the control circuit is used to determine the division of output voltage. The diode, MOSFETs, and comparator are also included in the control circuit, which allow the system to protect itself from any overload and also maintain the output voltage that is required by the system.
