TPS59641: Question about the SVID control of VCC_GFX (VNN)

Voyager Liao

Part Number: TPS59641

Dear Sir

We use TPS59641 as the VR solution for Intel Celeron Processor J1900.

Acoording to the datasheet of TPS59641, both VCC_CPU(VCC) & VCC_GFX(VNN) should be able to been controlled.

However, we found the VID Table of VCC_GFX(VNN) is fixed in the Intel Gen4 VR test tool ( VCC_CPU rail is fine to control VID)

Whcih means we can't change the VID parameter of VCC_GFX

Do you have any idea about this issue?

Thank you very much.

Hi Voyager,

You can use the panel on the bottom to control output voltage manually.

"Serial VID Test Vector Controls"

Thanks

Hi Chasel

Thanks for your advice, I will try that method.

For another question.

Can TI support customers to perform the VR Test Plan?

What conditions need to meet that TI will support us?

My company is Delta Electronics.

Thank you very much.
