Product Overview
out to base
These DC-DC converter modules use
advanced power processing, control and
packaging technologies to provide the
performance, flexibility, reliability and cost effec-
tiveness of a mature power component.
High frequency ZCS/ZVS switching provides
high power density with low noise and high
efficiency.

28 V Input
PRIMARY CONTROL - PC PIN
Module Enable / Disable
Module Alarm
The module may be disabled by pulling PC below 2.3 V with
respect to the –Input. This may be done with an open collector
transistor, relay, or optocoupler. Multiple converters may be
disabled with a single transistor or relay either directly or via
“OR’ing” diodes. See Figure 2.
The module contains “watchdog” circuitry which monitors
input voltage, operating temperature and internal operating
parameters. In the event that any of these parameters are
outside of their allowable operating range, the module will
shut down and PC will go low. PC will periodically go high
and the module will check to see if the fault (as an example,
overtemperature) has cleared. If the fault has not been cleared,
PC will go low again and the cycle will restart. The SC pin
will go low in the event of a fault and return to its normal
state after the fault has been cleared. See Figures 3 and 5.
Primary Auxiliary Supply
At 5.7 V, PC can source up to 1.5 mA. In the example shown
in Figure 4, PC powers a module enabled LED.

Output Voltage Programming
Parallel Operation
The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figure 8.
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy. Modules of the same input voltage, output
voltage, and power level will current share if all PR pins are
suitably interfaced.
Compatible interface architectures include the following:
+OUT
+S
AC coupled single-wire interface. All PR pins are connected to
a single communication bus through 0.001 µF (500 V)
capacitors. This interface supports current sharing and is fault
tolerant except for the communication bus. Up to three
converters may be paralleled by this method. See Figure 9.

constant current limit. Hence, available output power is
reduced by the same percentage that output voltage is
trimmed down. Do not exceed maximum rated output current.

PARALLEL BUS OUTPUT
•
•
The +Out and –Out power buses should be designed to
minimize and balance parasitic impedance from each
module output to the load.
+OUT
+S
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.
