Hi,
Customer has question about the PMBUS address for TPS546C23. In datasheet, we have below description:
The PMBus specification requires that each device connected to the PMBus have a unique address on the bus.
The devices each have 64 possible addresses (0 through 63 in decimal) that can be assigned by connecting
resistors from the ADDR0 and ADDR1 pins to AGND. The address is set in the form of two octal (0 to 7) digits,
one digit for each pin. ADDR1 is the high order digit and ADDR0 is the low-order digit.
so, if we used two 34.8k resistor for ADDR0 and ADDR1. the high side should 3(011), low side should be 3(011).
the real PMBUS should be 011 0011(33H) or 11011(27D=1BH)? which one should be right?
we have seen two kinds address in EVM board.
