Frequently Asked Questions

What output voltage range does the TL431AQDBVRG4 support?

The TL431AQDBVRG4 is adjustable from its internal reference voltage of 2.495V up to 36V, set by two external resistors connected in a voltage divider configuration at the reference pin.

How is the TL431AQDBVRG4 used in switching power supplies?

In SMPS applications, the TL431AQDBVRG4 serves as an error amplifier in the feedback loop. It compares the output voltage against its internal 2.495V reference and drives an optocoupler to regulate the output voltage with high precision.

What is the maximum current the TL431AQDBVRG4 can sink?

The TL431AQDBVRG4 can sink a maximum cathode current of 100 mA, which is sufficient for driving feedback networks and optocouplers in most power supply designs.

What package is the TL431AQDBVRG4 available in?

The TL431AQDBVRG4 comes in a 5-pin SOT-23 package, which is a very compact surface-mount package suitable for modern high-density PCB designs in portable and consumer electronics.
