| Feb 1, 2023 at 21:42 | comment | added | Justme | @SteveSh I am not assuming it. The OP confirmed that the same AUX winding is already powering the SMPS chip on the primary side. And that it needs to be isolated. | |
| Feb 1, 2023 at 20:55 | comment | added | SteveSh | Why do you assume that "the AUX winding is already powering the mains/primary side components"? There is nothing magical about this winding. It's just another secondary, in the general sense. | |

| Feb 1, 2023 at 16:30 | comment | added | John D | I think the OP's question should be rephrased as "Can I add (a possibly additional) auxiliary winding to a SMPS transformer to power additional circuitry. He's apparently not asking if the can use "the" auxiliary winding, which is typically supplying primary side circuitry. He also doesn't specify which side of the isolation barrier the additional circuitry is on, so if it's on the primary side he may be able to get away with stealing some current from the existing aux winding. | |
