MODEL:
MARGINING
During test and development, it is often required to
vary the output voltage around its target set point in
order to determine whether the load can operate over a
specified supply voltage range (Figure 8)
The NDM1-12 provides the ability to set the output volt-
age at a predefined higher or lower value around the
target set point. The Margin limit can be set through
the GUI or PMBus command. The output can be com-
manded to switch between the High value, Nominal or
Low value as a percentage of the nominal value. The
range can be set ±20% of the nominal target output
voltage value.
POWER FAULT MANAGEMENT
NDM1-12 supports the following fault conditions:
•
•
•
•
INPUT UNDERVOLTAGE LOCKOUT (UVLO)
A UVLO condition inhibits the output while the input
voltage is below the programmed threshold. The output
of the NDM1-12 will not turn on until the input voltage
exceeds the Vin UVLO Turn-On Threshold and will turn
off if the input voltage falls below the Vin UVLO
Turn-Off Threshold. The supported UVLO threshold
range can be programmed via PMBus from 8.5V to 14V.
In the continuous presence of a UVLO fault the
controller will make an infinite number of attempts to
re-start power control with no relaxation time between
attempts, allowing very fast system response once the
UVLO fault condition clears.

OUTPUT OVERVOLTAGE PROTECTION (OVP)
The NDM1-12 offers output overvoltage protection to
protect load circuitry from being subjected to a voltage
higher than its electrical specifications (limits).
The output of the NDM1-12 module will be turned off
and device will enter an OVP fault state when the out-
put voltage exceeds the pre-programmed OVP thresh-
old for a time greater than the pre-programmed hyster-
esis delay.
The module enters a hiccup mode and attempts to
restart every 250ms. A maximum number of 8 OVP
restart attempts every 250ms are made. Thereafter an
infinite number of re-start attempts are made every 1
minute. It will recover automatically when the output
voltage is reduced to less than the OVP limit.
A maximum number of 8 OVP restart attempts every
250ms are made. Thereafter an infinite number of re-
start attempts are made every 1 minute.
OUTPUT OVERCURRENT PROTECTION (OCP)
The device will enter an OCP fault state and the output
of the NDM1-12 module will be turned off if the load
current is 15-20% over the nominal load current. The
module enters a hiccup mode and attempts to restart
every 250ms. It will recover automatically when the
load current is reduced to less than the OCP limit. The
OCP threshold level can be programmed via GUI or
