The TL431 has been around for nearly 50 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this legacy device also found its way into alternative ...
Load current flowing through a precision resistor with predefined value (R1) produces a voltage that is compared with a given high-accuracy reference voltage (V R). Then, a feedback loop constantly ...
The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
