WEBENCH® Tools/LM5141-Q1: Simulation at 2.2MHz

Jared Becker

Part Number: LM5141-Q1

Tool/software: WEBENCH® Design Tools

Hi Team,

I would like to run a simulation with the LM5141-Q1 at 2.2MHz switching frequency. The datasheet specifically states that the device can run at 2.2MHz, but all my simulation results seem to be only available at ~400kHz. Is it possible to run a simulation at 2.2MHz?

Thank you,

Jared

Hi Jared,

What are your input design conditions? It is possible the min on-time or off-time limits might be limiting the frequency. Can you please share your design using the "Share Design" option with a public URL?

Amod

Hello Amod,

You are absolutely correct, it was an issue with the input design conditions. I changed the input voltage from 36 down to 24 and was able to switch to 2.2MHz.

Thank you for the support!
