Sets the output voltage when operation command is set to Margin
High. Programmed in VID Mode.
Sets the output voltage when operation command is set to Margin
Low. Programmed in VID Mode.
Sets the ratio of voltage sensed to current output. Scale is Linear
and is expressed in 1/ W
This offset is used to null out any offsets in the output current
sensing circuitry. Units are Amps
This sets the high current limit. Once this limit is exceeded
IOUT_OC_WARN_LIMIT bit is set in the Status_IOUT register and
an ALERT is generated. This limit is set in Amps.
This sets the output power over power warn limit. Once exceeded
Bit 0 of the Status I OUT Command gets set and the ALERT output
gets asserted (if no t masked)
