PMIC - Voltage Reference: TL431ACDCKR application field and working principle

TL431ACDCKR is a three-terminal adjustable voltage reference integrated circuit (IC) designed and manufactured by Texas Instruments, a world leading microelectronics producer. It’s a low cost and small size ideal solution for variety computer and consumer applications. Specifically, TL431ACDCKR typically used in battery charger circuits, input/output loops, switch mode supplies, as well as ASSP (Application Specific Standard Products). In addition to that, TL431ACDCKR is also widely used in industrial and general laboratory use, such as current sources, temperature controllers, voltage selectors and line drivers.

Key features of TL431ACDCKR

  • Integrated circuit: It is composed of an integrated circuit with a three-terminal adjustable voltage regulator.
  • Voltage reference: The voltage reference provided by TL431ACDCKR is about 2.4V to 36V with an output accuracy of ±0.5%.
  • Stability : TL431ACDCKR is highly stable and it takes only 10µs for its output to settle.
  • Quiescent current: The quiescent current is the current the IC requires to operate and is regarding 0.2mA.
  • Temperature ranges: The IC is rated to operate within a temperature range of -40°C to +105°C and it can withstand maximum of 125°C.

Working Principle

The TL431ACDCKR is mainly an adjustable voltage regulator. The output voltage is selected by the ratio of an internal fixed emitter resistor ("VEE") and an external feedback pin ("V-"pin) on which a potential divider voltage is applied. The external reference voltage is applied at the cathode of the voltage setting terminal (VREP pin). When the external reference voltage is greater than the reference voltage, the internal circuit operates the output transistor through the internal error amplifier.

The output voltage is determined by the voltage divider network at the negative feedback pin. An internal reference voltage is connected to the gate of the NPN transistor. When the negative feedback voltage exceeds the reference voltage, the transistor becomes active and causes a current to flow in the voltage output terminal. The output voltage is then determined by the external resistors of the feedback network. The internal reference voltage can be adjusted by an external resistor.

The TL431ACDCKR provides an adjustable voltage reference with a wide range of output voltage levels. It has a wide range of operating temperature ranges, low power consumption, and low quiescent current. The TL431ACDCKR can be used in battery charger circuits, input/output loops, switch mode supplies, and ASSP. The device is also used in current sources, temperature controllers, voltage selectors, and line drivers.

Conclusion

TL431ACDCKR is a three-terminal adjustable voltage reference integrated circuit designed and manufactured by Texas Instruments. It offers a low cost and small size solution for various computer, consumer and industrial applications. This IC provides an adjustable voltage reference with a wide range of output voltage levels, low power consumption, and low quiescent current. TL431ACDCKR can be used in battery charger circuits, input/output loops, switch mode supplies, current sources, temperature controllers, voltage selectors, and line drivers.
