    Hi Martin, thanks. It becomes a bit clearer what I could expect from the 40140 master/slaves configuration and what not: - Current sensing of higher CM voltages like 5.8V are done by a voltage divider, this is ok. - Over current protection of the slave…

    Kurt, The circuit looks correct. Verify that the OP-AMP selected can pull the ouptut low enough to hold the SS pin at 0.75V with the soft-start current forced across the diode. We need a pretty low minimum output voltage on the Op-AMP. If you need…

    While I do not support LM5117-Q1 directly, I can make some comments. Generally speaking, you cannot just tie the two outputs together. Usually the load currents will not be balanced. One converter will tend to run towards current limit. There are…

    Hi Guillermo, Yes, this part is as preferred to use for new design. TPS40140 and TPS40180 are the best stackable controller and they are very popular parts in TI. We have a lot of DINs along with NexFET recently. I don't think they will be obsoleted…
