Hi PI,
There is an approach for multiple output using tl431 according to image uploaded.
Feedback resistors designed as tl431 ref pin has 2.5V .
but...
How can this scheme be used for PS which has dual +5&-5V outputs in PI expert?
Regards.
This approach works for 2 positive outputs only.
In this case you can make the -5V output rail as Ground and then you will have 2 outputs +5 and +10 from which you get get the feedback.
