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.
