UCD90320: UCD90320

Part Number: UCD90320
Other Parts Discussed in Thread: UCD9090A,

We are using UCD90320 & UCD9090A.

Can we short PMBus of both to program with different addresses assigned ?

We are using one 5x2 berg header to program these.

  • Hi
    UCD90320 has 3 pins PMBUS_ADDRESS while UCD9090A has 2 PMBUS_ADDRESS pins.
    Do you do program pre-soldering?
    You can short UCD90320 PMBUS_ADDRESS pin. but for the UCD9090A, when the PMBUS_ADDRESS pins are shorted, the system runs at 10% slow clock. Yes, they will have different address. But I am very curious how you handle the address of UCD9090A in your final production?
