TPS79418DGNTG4

PMIC (Power Management ICs or Power Managed Integrated Circuits) are special of integrated circuits that provide the necessary electric current or voltage for other components within an electric or electronic circuit. Voltage Regulators are specially designed PMICs that help to regulate voltage levels within electric components and circuits. Linear Voltage Regulators are a type of voltage regulator that works by providing a central control voltage which is adjusted to regulate variations in input output current to provide steady voltage levels. This article will discuss the application field and working principle of the TPS79418DGNTG4 Linear Voltage Regulator.

Applications

The applications of the TPS79418DGNTG4 Linear Voltage Regulator can be seen in the automotive domain. The TPS79418DGNTG4 is designed to ensure that the wastegate control current stays within specific limits when a car is running. This Linear Voltage Regulator is especially useful in cars where engine monitoring and control is paramount, such as in vehicles with turbocharged engines.

Apart from automobiles, the TPS79418DGNTG4 is also used in precision measuring devices, especially in industrial control systems. Laser cutting systems, digital speedometers, and testing meters are some of the examples of equipment where the TPS79418DGNTG4 Linear Voltage Regulator plays an important role in maintaining steady voltage levels.

Working Principle

The internal structure of the TPS79418DGNTG4 Linear Voltage Regulator works by using a simple closed loop circuit. This circuit consists of an error amplifier which is used to determine how much output current is to be provided based on the feedback from the output voltage. This circuit also has an internal reference voltage as well as a circuitry for setting the output voltage.

When the output voltage increases, the error amplifier detects this and directs the output current to reduce. This, in turn, reduces the output voltage and corrects the imbalance. Conversely, when the output voltage decreases the error amplifier directs the output current to increase in order to increase the output voltage. This process continues and the output voltage remains within a specified limit.

Conclusion

The TPS79418DGNTG4 Linear Voltage Regulator is a useful device which can be used in a range of applications. Its internal closed loop circuit aids in the regulation and stabilization of voltage outputs and provides precise voltage levels where accuracy is required.
