To allow PMBus devices to map between the nominal commanded voltage and the voltage at the control circuit input FB (VOUT divided down to match the reference voltage EA_REF), the device uses the
Table 1 lists the range of valid VOUT_COMMAND values which are dependent upon the configured
VOUT_SCALE_LOOP (29h) command.

|OUTPUT VOLTAGE RANGE (V)||VOUT_COMMAND
DATA VALID RANGE
If the value programmed to VOUT_COMMAND exceeds the value stored in either VOUT_MIN or VOUT_MAX. In this case, VOUT_COMMAND will be set to the appropriate VOUT_MIN or VOUT_MAX value (which ever was violated). For the specific status bits set in either case, see the command descriptions for the VOUT_MIN (28h) or VOUT_MAX (24h) command.
