Original question:

LM4871: Problem with pspice simulation

LM4871: Problem with pspice simulation (cont)

Paul Andrews

Part Number: LM4871

In my previous thread about this, Ivan Salazar said he would get back to me in around a week. That was a month ago and I note that the thread is now locked. This was the text of that thread:

I am trying to run a simulation of a design that uses the LM4871, in the TI version of pspice. However, I get this error:

ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U1.XU11.EVCM. You may break the loop by adding a series resistance

which looks like it is a problem with the LM4871 pspice model (U1 is the reference of the LM4871 component).

I'm new to pspice (I have used LTSpice in the past), so it could be me. Has anyone successfully used this model before?

    Hi Paul,

    I apologize for the delay on this solution, I'm reserving some time to go over this and provide some feedback next Monday or sooner if possible.
    Will keep you updated if anything changes but I expect this to be only a matter of changing voltage controlled source in the source code.

    Best regards,

    Hi Paul,

    I'm testing this out tonight, will update as soon as this is complete.
