Hello, 

 

From the supported VR list(tested) , only LTC3882-1 listed. 

The PMBUS controller should be the same, but can you check below codes in your firmware:

 

LTC3882

------------

PAGE = 0

VOUT_COMMAND -> sets output 0 only

PAGE = 1 -> not supported

 

LTC3882-1

----------------

PAGE = 0

VOUT_COMMAND -> output 0

 

PAGE = 1

VOUT_COMMAND -> output 1

 

if the firmware used LTC3882-1 on LTC3882 device, this explains the 0x14 reply from Analog Device (command acknowledged, but not supported/incorrect mode")

 

regards,

Farabi
