Part Number: TL431C Other Parts Discussed in Thread: TL431 Hi
I am using TL431cvin flyback SMPS application to regulate 15v. But TL431c is getting turn ON even though the Veer<2.5V. it's getting turn ON at veer=1.18V. we expect it supposed to ON at Veer…
Other Parts Discussed in Thread: TL431C Hello,
We selected the TL431C for our design. However, we are having some issues in our system, and may have traced it back to this device. It has 2% tolerance, but we need some clarification on what that means. …
Upon additional study, I see that the Dynamic Impedance of the common model TL431C is: V KA = V ref , f ≤ 1 kHz, I KA = 1 mA to 100 mA . Is the difference that the TLCLP-Z begins regulating at 400uA, whereas the TL431C begins regulating at 1mA?
Hi SHH,
VI(dev) is the deviation voltage from the internal bandgap reference over full temperature range. The larger the number, the more it deviates from the original reference voltage and causes inaccuracy. The smaller the VI(dev) the better.
Looking…
