Figure 11 — N+1 module array output connections.

•

The +Out and –Out power buses should be designed to

minimize and balance parasitic impedance from each

module output to the load.

•

The +Sense pins must be tied together to form a

+Sense bus. This must be Kelvin connected to +Out

at a single point. The –Sense pins should be tied

together to form a –Sense bus. This must be Kelvin

connected to –Out at a single point.

•

At the discretion of the power system designer,

a subset of all modules within an array may be

configured as slaves by connecting SC to –S.

•

OR’ing diodes may be inserted in series with the

+Out pins of each module to provide module

output fault tolerance.

•

The +Sense and -Sense leads should be routed in close

proximity to each other on the printed circuit board. If

wires are used to connect the converters on a PCB to

an external load, the Sense leads should be twisted

together to reduce noise pickup.
