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 fault limit. Once exceeded Bit
1 of the Status I
asserted (if not masked).
This sets the output power over power warn limit. Once exceeded Bit
0 of the Status I
asserted (if not masked)
