TPS544C25: Not using PMBus?

Part Number: TPS544C25
Other Parts Discussed in Thread: 66AK2H14

Hello, I'm planning on using the TPS544C25 Synchronous Buck Convertor to provide the Smart Reflex power on the 66AK2H14 DSP+ARM processor. I do not plan to use a PMBus and would like to know what I do with the PMBus pins ADDR0, ADDR1, CLK, CNTL, and DATA pins?

Hi,

I am not quite familiar with this part but from the sample evaluation board, it seems that they route the PMBus pins to a header and they have a pull up resistor on the address pin

Thanks

Thanks Arief. I'll look at that document. The part should be able to work without anything on that header.
