[Test environment]
1. We purchased "TPS546C20AEVM1-746" to use "PS546C20A".
2. We have successfully tested VOUT from 0.35V to 1.6V in the following environment.
"TPS546C20AEVM1-746" - (USB-TO-GPIO) - "PC (FUSION_DIGITAL_POWER_DESIGNER)"
3. Next, "MCU (ATmega128A) Test Board" was connected instead of PC as in the following environment.
"TPS546C20AEVM1-746" - (2 wire Cable) - "ATmega128A Test Board"
[Question]
Q. We want to check only the PMBus communication test between "PS546C20A" in EVM and MCU (ATmega128A-i2C)
Can I connect only "CLK" and "DATA" like the attached file for this?
Or do I have to connect the other two lines (CNTL, SMBALRT)?
(But we will not confirm until "VOUT" yet)
