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 OUT Command gets set and the FAULT output gets
asserted (if not masked).
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 not masked)

A fault was declared because the NCP4201
was busy and unable to respond.
This bit is set whenever the NCP4201 is not
switching.
This bit gets set whenever the NCP4201 goes
into OVP mode.
This bit gets set whenever the NCP4201
latches off due to an overcurrent event.
A Communications, memory or logic fault has
occurred.
A fault has occurred which is not one of the
above.

This bit is set whenever the
NCP4201 is not switching.
This bit gets set whenever the
NCP4201 goes into OVP mode.
This bit gets set whenever the
NCP4201 latches off due to an
overcurrent event.
A Communications, memory or
logic fault has occurred.
A fault has occurred which is not
one of the above.
This bit gets set whenever the
measured output voltage goes
outside its power good limits or
an OVP event has taken place,
i.e. any bit in Status V OUT is set.
This bit gets set whenever the
measured output current or
power exceeds its warning limit
or goes into OCP. i.e. any bit in
Status I OUT is set.
A manufacturer specific warning
or fault has occurred.
