Hi team,

Customer wants to use multiple EVM(max 4) by one PC.

Q1. Is this possible?

Q2. It it possible to install multiple identical software(SBOC417 — BUF22821EVM-USB User Software) to one PC? If possible, how?

Best regards,

Hi Goto,

Do you mean use one PC for 4 EVMs at the same time? Like programming the output voltage for the 4 EVMs together?

Hi Shuhei,

BUF22821 has only two I2C address to distinguish different IC, so with 4 EVMs I am concerned the communication between PC and IC will have unexpected influence.

Hi Patrick,

Thank you for letting me know.

So, does that mean we need four PCs to handle four EVMs?

Best regards,

Hi Shuhei,

If you need to operate the 4 EVMs at the same time, then more PCs are needed. If you only need to program the output voltage, you can use one PC to program the output voltage of the 4 EVMs one by one, just keep the EVMs are powered on.
