TLE4278GXUMA1 PMIC - Voltage Regulators - Linear Application Field and Working Principle

The TLE4278GXUMA1 is an adjustable voltage regulator compatible with the PMIC - Voltage Regulators - Linear family. It is designed to provide an adjustable output voltage with guaranteed maximum output current of 10A. This device can be used to regulate the output voltage of an electronic circuit from 1.2V to 12V.

Overview

The TLE4278GXUMA1 is a PMIC (Power Management Integrated Circuit) that provides an adjustable output voltage with a maximum output current of 10A. It is designed for applications that require an adjustable output voltage but do not require the highest level of efficiency. The device includes a built-in error amplifier and an external resistor divider for setting the output voltage. The device also includes an integrated current limit and thermal protection for increased reliability and safety.

Features

* Adjustable output voltage from 1.2V to 12V* Maximum output current of 10A* Built-in current limit* Thermal protection* Low quiescent current of 140µA* 16-pin VQFN package

Applications

The TLE4278GXUMA1 is ideal for applications that require an adjustable output voltage while maintaining a high level of reliability. Examples of such applications include computers, notebook PCs, consumer electronics, and printer supplies.

Working Principle

The TLE4278GXUMA1 is a linear voltage regulator, which means that it works by regulating an input voltage to the desired output voltage. The device includes an error amplifier and an external resistor divider network for setting the output voltage. When the voltage of the external resistor divider is lower than the desired output voltage, the error amplifier will increase the output voltage until it is equal to the voltage of the resistor divider. On the other hand, when the voltage of the external resistor divider is higher than the desired output voltage, the error amplifier will decrease the output voltage until it is equal to the voltage of the resistor divider. In addition, the TLE4278GXUMA1 also includes an adjustable current limit, which limits the maximum output current to the desired value. This can help to protect the device and the application from any large current surges. Finally, the device also has a thermal protection circuit, which will shut down the output voltage if the temperature of the device exceeds the maximum operating temperature.

Conclusion

The TLE4278GXUMA1 is a PMIC - Voltage Regulators - Linear device designed to provide an adjustable output voltage with guaranteed maximum output current of 10A. It can be used in a wide range of applications that require an adjustable output voltage but do not require the highest level of efficiency. The device includes a built-in error amplifier, an external resistor divider, an adjustable current limit, and a thermal protection circuit to ensure safety and reliability.
