TLV62085: FB pin connection for 0.8V output

Part Number: TLV62085

Hi,

For 0.8V output application, Webench recommend connect it as pic below, or I can just connect FB to output without Rfbt and Rfbb.

Thank you.

Hello Chentsu,

Thank you for the interesting question.
You can actually connect the output to the feedbak and leave Rfbb open.
The result you get from Webench is due to the artefact of the impossibility to handle "infinite" as a number.

Enjoy your design!

Thanks and best regards,
Emmanuel
