CONTROL FUNCTIONS - 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 1.
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 2 and 4.
Primary Auxiliary Supply
At 5.7 V, PC can source up to 1.5 mA. In the example shown
in Figure 3, PC powers a module enabled LED.

Trim Up
Trim Down
1. The converter is rated for a maximum delivered power. To
ensure that maximum rated power is not exceeded, reduce
maximum output current by the same percentage increase in
output voltage.
1. This converter is not a constant power device – it has a
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.
2. The trim up resistor must be connected to the +Sense pin.
2. The trim down resistor must be connected to the –Sense pin.
3. Do not trim the converter above maximum trim range
(typically +10%) or the output over voltage protection
circuitry may be activated.
Trim resistor values calculated automatically:
On-line calculators for trim resistor values are available
on the vicor website at: vicorpower.com/tools.
Resistor values can be calculated for fixed trim up,
fixed trim down and for variable trim up or down.
In addition to trimming information, the web site and
the Applications Manual also include design tips,
applications circuits, EMC suggestions, thermal design
guidelines and PDF data sheets for all available Vicor
products.

CONTROL FUNCTIONS - PR PIN
Parallel Operation
+IN
PC
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy and phased array capability. Modules of
the same input voltage, output voltage, and power level will
current share if all PR pins are suitably interfaced.
Module 1
PR
–IN
Compatible interface architectures include the following:
+IN
PC
DC coupled single-wire interface. All PR pins are directly
connected to one another. This interface supports current
sharing but is not fault tolerant. Negative In pins must be tied
to the same electric potential. Up to three converters may be
paralleled by this method. See Figure 9.
Module 2

PR
–IN
Ground plane
Figure 9 — DC coupled single-wire interface.
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 10.
