PMIC - Voltage Reference: TL431AIZ Application Field and Working Principle
TL431AIZ is a popular three-pin adjustable shunt regulators/voltage references. It is widely used in various fields, and demonstrates multiple features that make it one of a kind. It features a temperature-coefficient ratio of 10 ppm/°C, a closed loop voltage variation of ±0.5%, and a reference impedance of 0.1%. This article provides an overview of the major application field of TL431AIZ and how it operates.
Application Field
The widely used applications of TL431AIZ includes:
- Current and impedance control
- Lighting control
- Photovoltaics
- Battery charging
- Voltage regulators/regulator/power inverters
- Motors and motor drives
- Electronic ballast
It is also used in various system control and feedback applications. It is well suited to adjusting a variety of LED drivers and LED light systems. It is also used in automotive signal processing and electronic measurement circuits. TL431AIZ is an ideal choice for the development or design of power supplies and other power electronics applications.
Work Principle
TL431AIZ is basically a precision shunt regulator that consists of an internal zener reference, an error amplifier, and an output driver. It runs from an operating current of up to 100mA, with a voltage range of 0-36V. The internal zener reference acts as the reference current for the circuit and regulates the output voltage level. The error amplifier then compares the current generated by the reference with the current generated by the output driver, and adjusts the output voltage accordingly. Finally, the output driver amplifies the signal generated by the error amplifier and controls the output voltage.
When the output voltage deviates from the reference voltage, the error amplifier will try to fix it by adjusting either the reference voltage or the feedback voltage. The reference voltage is usually adjusted automatically by changing its current supply, while the feedback voltage is typically adjusted manually by changing a potentiometer. The entire process occurs within a few microseconds and ensures that the output voltage remains stable and accurate.
Conclusion
TL431AIZ is a versatile shunt regulator/voltage reference that can be used in many fields for a variety of applications. With a temperature coefficient of 10 ppm/°C, a closed loop voltage variation of ±0.5%, and a reference impedance of 0.1%, it provides stable, accurate and reliable performance. The internal circuitry of TL431AIZ makes it a great choice for applications that require precise control of voltage levels and current levels.
