WEBENCH® Tools/LM25145: UVLO Implementation for Input Transient Simulations

Antonio Fadhel

Part Number: LM25145

Tool/software: WEBENCH® Design Tools

Hi team,

My customer is simulating the LM25145 on Webench with a 49.9k Ruv1 and a 7.15k Ruv2 for a UVLO around 9.5V. However, when they run an input transient simulation it seems to regulate the output with Vin as low as 6V (see below). Does the model used for the input transient sim take UVLO into account?

Thanks,

Antonio

Hi Antonio,

We have found the issue which is causing steady-state simulations to disable UVLO functionality.
We are working on it and will update you after we modify the model on Webench.

Thanks,
Abhisek

Hi Antonio,

We have fixed the issue with respect to UVLO functionality of this device on Webench. However you will be able to observe the changes on http://www.ti.com/product/lm25145 by next week.

Please feel free to revert back in case you need any help.

Thanks,

Kiran Kumar
