MP8856 PMBus Interface Specifications (Hs-Mode)

DC-DC Power Converters

It says SCL Clock Frequency 400kHz(typical) and1000kHz(Maximum) in PMBus Interface Specifications.
In general,PMBus Interface clock should has 10kHz(minimum) in HS-MODE,shouldn’t it?
Also, do you have the reference material of PMBus Interface(HS/LS-MODE is supported on MP8856)?

Hello Shinichiro-san,

I believe the 400kHz - 1MHz frequency range is referring to the switching frequency of the power stage and not referring to the clock frequency of the SCL PMBus Interface.

For further reference material, please submit a ticket to the following link to receive this information directly: Contact MPS - Design Assistance and Resources Contact
