QPI Application Circuits:

Filtering Dual Converters

The shield plane under the two converters in Figure 13 should

be one contiguous plane under both. The circuit in Figure 13 is

capable of filtering more converters than shown, up to the

maximum current limit of the QPI-6. In Figure 14, a separate

shield plane is required for each converter along with a

separate RY resistor.

The QPI-6 is not designed to be used in parallel with another

QPI-6 to achieve a higher current rating, but it can be used

multiple times within a system design.

Filtering Parallel Converters

Note 4: In Figures 12 and 13; CIN1 and CIN2, CY1 through CY8, should be the value and voltage rating recommended by the converter’s manufacturer.
