Hi David,

Thank you for your interest in LM51571.

I will help review the schematic and get back to you. By the way, do you have the link to your Webench? It is supposed to have the compensation calculation so I need to fix that as well.

Thanks,

Yinsong

Thank you, David.

A few questions.

1. Where is the BIAS_BST connected to?

2. I saw there are compensations show up?

The others look ok to me.

Thanks,

Yinsong

Hi Yinsong,

thank you for the replay.

1) There should be 0R between BIAS_BST and Vin which is missing, i will fix this

2) I don't understand the question

Best Regards,

David.

Hi David,

I mean the Webench has created the compensation network for you, i.e., Rcomp, Ccomp, and Chf, if that's what you were asking for.

Please let me know if there is any questions.

Thanks,

Yinsong
