TPS549D22: VOUT_COMMAND, Is it really NVM?

Expert 6010 points

Part Number: TPS549D22

 Hello,

 

I have a question about a PMBUS command, “VOUT_COMMAND”, of TPS549D22.

 

From the datasheet, VOUT_COMMAND is NVM. Is it really NVM?

 

I tested it with TPS549D22EVM-784 and Fusion Digital Power Designer.

I changed VOUT_COMMAND value on the Fusion Digital Power Designer and confirmed the Vout was changed as configured.

And push “Store Config to NVM”. It should be saved to NVM.

But after new powering cycle, the it was NOT saved.

 

Regards,

Oba
