LM5146-Q1: simulate steady-state model of LM5146-Q1 PSpice Unencrypted Transient Model (Rev. A) in PSpice for TI

VIPIN KUMAR

Part Number: LM5146-Q1

I am trying to simulate steady-state model of LM5146-Q1 PSpice Unencrypted Transient Model (Rev. A) in PSpice for TI but every time I got the startup model result.

https://www.ti.com/product/LM5146-Q1?keyMatch=LM5146-Q1&tisearch=search-everything&usecase=GPN#design-tools-simulation.

What should I do for steady-state simulation.

Hi Vipin,

Please increase your simulation run time long enough for the model to finish startup and reach steady-state.

Hello Rahil

I have attached the simulation file. Please tell me how much I can increase the simulation time so that I can get the both startup and steady state result at a time.

regards

Hi Vipin,

It looks like it takes about 3.8ms to reach steady state. Please try running the simulation for 4ms or higher.
