Tl431 smps calculator. The output drives a bipolar transistor, actually making the TL431 a shunt regulator: when the voltage on the reference pin (R) is below 2. This application note will address output control techniques for linear and switch mode power supplies (SMPS). As soon as the voltage exceeds the reference, the transistor starts to conduct and a current circulates inside the device. Use internal reference voltage = 2.
