TPS56121: Simulation with TPS56121 library

moon kye

Part Number: TPS56121

Regarding TPS5621 simulation, i am using Pspice-TI. I got the library on the Pspice and build the circuit.

I want to AC simulation to get the bode plot. before that i did transient one first to make sure the circuit is working.

But there is no error on simulation but it seems not working. No output and no switching.

Has anybody seen this kind of issue ?

Please advise me.

Thanks,

Moon

Are you using the average model for the ac simulation.

The transient model will not work for the ac simulation

Thanks for your help.

You did something different method from what I know.

One question is "Do you have other model to simulate the transient ?"

yes, there are different models on the product folder

This is the transient model for the tps56121
