Hi,
Is there a reason why the spice model for the TL431 seems to make use of node 0 which as global ground, prevents its use as reference to negative regulation?
This is particularly critical in more complex circuits such as multi-output SMPSs, where relocating grounds to make sims work is just not practical.
.SUBCKT TL431 7 6 11
* K A FDBK
R_R18 0 N16955548 1 TC=0,0
Why?
Moreover, other models that don't use node 0 seem to work fine.
If I am correct, can you please offer a model that is not internally tied to node 0?
Thanks in advance for your help
