The –IN lugs must be connected together if the paralleling connector is used, or if the EN, TR,
or FT pins are interconnected in any fashion. However if all control signals of all DCMs are fully
isolated from one another, then both the +IN and –IN lugs can remain independent across the
evaluation boards, and the DCMs can be operated with fully independent input supplies.

Standoffs must be sufficient in length to avoid contact between boards, and to permit airflow to
all DCMs in the system.

If coordinated enable control, trimming or fault monitoring is desired, then the paralleling connectors
J09 & J10 can be used to easily interconnect the PRI_FT, PRI_EN, PRI_TR_ and PRI_FT
nodes across boards.
The paralleling connectors at J02 & J03 can be used for coordinated enable and trim control and fault
monitoring. The enable, trim and fault monitor features of the top most board should be used for
convenience, while the remaining boards should have their jumper blocks depopulated and enable
switches set to enable.
The paralleling wire-to-board connectors (at J02 and J03) are provided to daisy chain control signals and
PRI_SG, with a simple strip and insert option. They will accept 18 – 24 AWG solid wires.
