and C1-C4 should be the values recommended by the converter manufacturer.
If the manufacturer does not specify a value for the Y-capacitors use 4.7nF. Ry=10

QPIs will filter multiple DC-DC converters up to the
maximum current rating. The schematic in
Figure 7
shows the required circuit for multiple DC-DC
converters. The Shield Plane should be added under
each converter as a common EMI Shield. Note that only
a single RY is required in a multiple converter
configuration.
If higher attenuation is required, QPIs can be
connected in series.
Figure 8
shows the proper
schematic for QPIs in series. Note that only one RY is
required in this configuration.
The QPI can also be used to filter embedded or “down”
converters made up of discrete components. Where
ever possible a Shield Plane and Y-capacitor decoupling
should be included in the embedded converter design.
Follow the circuit and layout recommendations for a
brick converter shown in
Figures 7, 9 & 10
.
Thermal Considerations
The current derating curve shown in
Figure 5
should be
used when the PCB temperature in close proximity of
the QPI-6 exceeds 60°C. For example, the QPI-6 will
support up to 13 A of current or 528 W from a 48 Vdc
bus at an 80°C interface temperature. Temperature
should be measured at the PCB interface to the QPI-6
on the Bus +/- pads or the QPI+/- pads. Refer to
Figures
9, 10 & 12
for PCB layout recommendation.
