CONTROL FUNCTIONS - PC PIN
Module Enable/Disable
Module Alarm
The module may be disabled by pulling PC below 2.3V 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 5.7V, PC can source up to 1.5mA. In the example shown in
Figure 3, PC powers a module enabled LED.

Figure 7—Output voltage trim down circuit.
Figure 8—Output voltage trim up circuit.
Trim Down
Trim Up
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.
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.
2. The trim down resistor must be connected to the –Sense pin.
2. The trim up 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.html.
Resistor values can be calculated for fixed trim up, fixed
trim down and for variable trim up or down cases for both
1st and 2nd Generation DC-DC converters.
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
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.
Compatible interface architectures include the following:
