USB-TO-GPIO: How to use 2 TI programmer (USB-TO-GPIO) to program 2 TPS544B25 with same PMBUS address

Wei Shin Ng

Part Number: USB-TO-GPIO

I have 2 TI programmers that are connected to 2 TPS544B25 (on 2 separate but identical boards) with the same PMBUS address. How can I use TI Fusion Digital Power Designer software that is installed on the Windows PC to program the 2 TPS544B25 separately using the FusionConfigWriter.exe without disconnecting either one of the TI programmer at any one time?

Thank you.

It is a spec violation to have two devices on the same physical bus at the same time. If they are on two separate buses, you would need to configure them serially by disconnecting either one of the TI programmers or providing two Windows PCs.
