TPS54425: Design Considerations of VO Pin in ICs

ryuichi.a.sakai

Part Number: TPS54425

Hello.

I have a couple of questions regarding ICs, specifically about the VO pin.

What is the role of the VO pin in ICs? Is it an input pin?

I couldn't find detailed information about the VO pin in the datasheet. Could you please provide some insights into its functionality and whether it is an input pin?

In terms of design, what considerations should be taken into account for the AW pattern?

I would greatly appreciate it if you could provide any guidance or recommendations on how to design the AW pattern.

Hi,

The VO pin is a direct sense of output voltage so it's an input pin. When Vout drops, this pin can detect it immediately and start next period to achieve best transisent performance.

What is AW pattern? Could you explain it?

Thanks.

Regards,

Shipeng

Thank you for your response.

AW is an abbreviation for Artwork. AW pattern refers to PCB layout.

Do you have any recommendations for the PCB layout of the VO pin?

Hi,

You can see our LAYOUT CONSIDERATIONS in datasheet, or layout picture in EVM user's guide. Thanks.
