Hello all!
Last week I asked to your support team about Figure 10 of the UC3525 datasheet. I was worried about how this circuit could work and I asked for a example. Without answers.
See, in a first sight this circuit converts from push-pull to parallel mode (single ended), isn't? I tried in many ways to implement this circuit and simply it doesn't work properly. I see that the root of the issue could be how the output stages were build. If you check the Figure 09 you will see that transistors Q9 and Q10 has the same power sourse, so It is a vicious circle.
So at this point I seached on internet and nobody implemented this circuit in this way. The best option I found was to put fast response diodes in the outputs A and B and merge they together.
My question is, please could you (TI or somebody) show me how do you think that this circuit could work? could you share a functional example? and if it doesn't work, why is present in the datasheet?
Thanks so much!
