LM5022 Spice Model

Other Parts Discussed in Thread: LM5022

Hello everyone,

I am using the program SIMetrix 7.1 for simulation of some designs. Right now I have errors while trying to simulate a design containing the LM5022 PSpice model.

Following notification pops up:

There are errors in the circuit. Simulation aborted
design.net (7): LM5022$U1 V1_P R3_P V1_P C1_P R2_N U1_FB U1_VCC 0 0 U1_OUT LM5022_TRANS
*** ERROR *** Unknown parameter 'C1_P'
*** ERROR *** Unknown parameter 'U1_FB'
*** ERROR *** Unknown parameter '0'
*** ERROR *** Unknown parameter 'U1_OUT'

I checked my netlist and so on without finding any error in it. Did someone encounter a similar problem with the LM5022 model and knows how to fix this issue? It would help me a lot.

Thanks, Florian.

Florian,

I do not recognize the Errors, but I am not that familiar with SiMetrix. The PSpice models in the product folders are encrypted and can only be used in PSpice version 15.7 or higher. You will need the unencrypted PSpice model to use the device in SiMetrix. If you have a direct TI support contact, they can request the unencrypted model for you. If not, please refer to the following post for how to request the unencrypted model:

Hi Britt,

thanks for your response. In the meantime I found a similar post about another SIMetrix model in the forum.

You still helped me a lot, thanks.
