CONTROL FUNCTIONS - PR PIN (CONT.)
• 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 should be tied
to the same point on the +Out
power bus; the –Sense pins
should be tied to the same point
on the –Out power bus.
• At the discretion of the power
system designer, a subset of all
modules within an array may be
configured as slaves by shorting
SC to –S.
• ORʼing diodes may be inserted in
series with the +Out pins of each
module to provide module output
fault tolerance.
