Digital Power-Supply Controller/Monitor
with PMBus Interface
The MAX8688 uses DIRECT format for all parameters with
the exception of manufacturer-specific commands. Refer
to the manufacturer command details on data format.
The host system uses the following equation to convert
the value received from the PMBus device, in this case
the MAX8688, into a reading of volts, amperes,
degrees Celsius or other units as appropriate:
