Hi,
I am a beginner with PMBus. I am trying to understand the difference between I2C and PMBus. I understand PMBus standard is based off I2C spec.
Do systems have different PMBus and I2C bus, or can the same bus be used for serial communication between power management IC's and other IC's?
Are the capacitance limits for PMBus the same as I2C bus (400 pF for Fast mode?).
Thanks,
Rajan
