LM25005: What is the correct switching Frequency range?

Part Number: LM25005

Hello,

The datasheet states switching frequency range is 50KHz to 500KHz.

However, WeBench shows it is 150KHz to 1MHz as follows.
Which is true?

Hi Kazuhiko-san,

I believe the datasheet is the correct information. I will communicate to webench about the frequency on webench.

Thank you for pointing that out

Arief,

Thank you for your response.
Please communicate to WeBench about it.
If WeBench is correct, customer Fsw on the following E2E thread is around 1MHz, it should be also correct.

Hi Kazuhiko-san,

I have moved the thread in webench for the switching frequency question.

Thank you

Hi Kazuhiko-san,

Thanks for contacting us. We will update the Frequency range to 50KHz to 500KHz as per datasheet.
The fix will be reflected on ti.com in the next release cycle. We will let you know once it is done.

Thanks and Regards,
Veeranna

Veeranna,

Thank you for your response.
I understood that the datasheet is correct and WeBench is wrong.
Around when do you think the next release cycle will be?

Best regards,
