can be added as shown in Figure 15. The GUI automatically changes values of the IBL and IBH
thresholds when the reference selection is changed.
Note: If the Reference Voltage setting is changed during operation of the DPM, then the power to the DPM
U1 and R1 are additional components. U1 is an industry standard 2.5V voltage reference such as
TL431 or similar. C1 is an existing component but its value changes depending on the type of voltage
reference. Common voltage reference part numbers and values of associated components are shown
in Table 4.
Accuracy of the protection thresholds in the case of external reference is determined by the sum of
accuracy of the voltage reference, accuracy of the 10k/47k resistive divider shown in Figure 15, and
conversion error of the internal ADC specified in 8.2.

POL converters and Auxiliary Devices can be arranged in up to four groups. A group of POL converters
is defined as a number of POL converters with interconnected OK pins. Auxiliary Devices are added to
a group in the GUI, without any external connections. A group can include from 1 to 32 POL converters,
but a POL converter can be a member of only one group. In addition, the OK lines can be connected to
the DPM to facilitate propagation of faults and errors between groups. One DPM can manage up to four
independent groups: A, B, C, and D, depending on model of the DPM.
Group management includes fault and error propagation, margining, turn-on and turn-off, monitoring
setup, and interrupt configuration.
