TPS546C20A: PMBUS Master-slave address settin

user1932012

Part Number: TPS546C20A

Is the TPS PMBUS master-slave address set only in 36d/37d? Do you need to set up on the hardware? If the hardware is set up, I am sending 36d/37d address, how can I confirm that is the master, that is from.

Mark,

Let me look into this. It may take a couple days.

Mark,

Yes the master and slave addresses are fixed and cannot be changed. No added hardware is necessary. 36d is always the loop master, 37d is always the loop slave (if you are using 2 TPS546C20A in a stacked configuration).
