66AK2E05: CVDD AVS Power module selection

Tarang Jindal68

Part Number: 66AK2E05
Other Parts Discussed in Thread: TPS544B20

Hello Sir,

We want to use TPS544B20 for K2E SoC CVDD power design.

But this IC only support PMBus AVS implementation.

Please let me know is there any application note for PMBus AVS implementation for K2E SoC.

If there is a App note for the same, please provide the link.

Thanks and Regards

Hello sir,

Thanks for the application notes.

These app notes talks about the hardware implementation of AVS using PMBUS.

is there any app note available which provide information regarding software side of PMBus used for AVS implementation.

At power on, SoC is not configured then how SoC will calculate the "VOUT_Command" value and provide this calculated value to PMBus.

Please help me to understand this concept.

Also, We are not using BMC section in our design, so, is it possible to use PMBus interface to set the AVS supply? if yes then how? Please answer.

Thanks and Regards
