TPS51385: Simulation error Pspice for TI

Erika Long
Intellectual 1200 points

Part Number: TPS51385

Tool/software:

Hello,

I am attempting a transient simulation of TPS51385 with an input at 12V and output of 3.3V. I have attached the archived file. The simulation runs, but I am seeing an output voltage of around 1.3V and switching starts in the beginning of the simulation but stops around 4ms. Is there an error in my circuit that is not allowing the simulation to run at the designed parameters?

    Hi,

    Your application is a normal application. It is likely that there are some configuration problems in the simulation convergence. However, you may need to contact the Pspice team for the specific error. It is recommended that you use the webench model or the parameters recommended in our datasheet. If you want to verify it in practice, you can also use our EVM. Thanks.
