Hi, again!
Another TL431 question ....
I would like to make my PSU soft-start. I was looking at the TL431 datasheet, to figure out how can I make this IC to "do" soft start.
Will that work, if I put a capacitor and a resistor paralell with the resistor, which is between the cathode, and the "reference" pin? Or this will caouse problems in the feedback loop? If I put a relay series with the R-C, and that relay "disconnects" that R-C after a short time, will this work?
BTW, I found a schematic in TL431's datasheet, on figure 27, but I don't think that will be good for me. That's only "delay", not soft-start.
Thanks in advance!
