Description
A simple simulation of the PG pins on the TPS54394 SMPS from TI.
There is a TI PSpice model for the TPS54394:
https://www.ti.com/lit/zip/slvm613
It should run ok in LTspice as used on EasyEDA but:
1) A Spice Symbol will need to be created for it and;
2) It may found that the simulation will hit the EasyEDA run time/resources limit before the simulation runs long enough to show a useful elapsed time from start up.
It may therefore be better running a simulation on a locally installed copy of LTspice or on the PSpice tools that TI supply.
If however all that is required is to study a design for a LED driver from the PG pin then this simulation is adequate.
