Figure 6 – Recommended schematic for QPI. Values of CIN 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=10Ω, 1/4 W.

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-2 exceeds 60°C. For example, the QPI-2 will
support up to 10 A of current or 280 W from a 28 Vdc
bus at an 80°C interface temperature. Temperature
should be measured at the PCB interface to the QPI-2
on the Bus +/- pads or the QPI+/- pads. Refer to Figures
9, 10 & 12 for PCB layout recommendation.
