TPS552892: Simulation error: Undefined Parameter - Fast_Startup

Abhishek Tiwari

Part Number: TPS552892

Hi,

I tried simulating the Pspice model on Pspice for TI. It gives the error, undefined parameter Fast_Startup. Any idea what this is?

Best Regards

Hi Abhishek,

Thank you for reaching out. What the the input voltage range, output voltage, and output current? What kind of simulation do you want to perform? May I know what is the application? I will help check the simulation model later.

Regards,

Mulin

Hi Mulin,

the input voltage range is 6-36V and output current max is 2A and output voltage 6V. I want to simulate the functionality throughout the input and load range and verify the design(transient analysis mainly). Would like to see the bode plots as well if it correctly models that.

Thanks

Abhishek

Hi Abhishek,

Thank you for your waiting.

This is because in your simulation project, there lacks some library documents.lib document.zip

Add these files in the project will help solve the problem.

Meanwhile, I have concern that the simulation model you set up is unclear(might have connection problems) and difficult to debug in your follow-up simulation. Strongly recommend to download the simulation from our product page: https://www.ti.com/product/TPS552892?keyMatch=TPS552892&tisearch=search-everything&usecase=GPN-ALT

Or use this file for simulation.slvme05.zip
