Product Overview
This DC-DC converter module uses
second generation power processing, control
and packaging technologies to provide the
performance, flexibility and cost effectiveness
expected of a mature Power Component.
For example, a plated-cavity core transformer
couples widely separated primary and
secondary windings, resulting in low in-to-
out parasitic capacitance and noise.
High frequency ZCS/ZVS switching,
advanced power semiconductor packaging
and thermal management provide high
power density with low temperature
gradients. Extensive use of silicon

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, 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.

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 up resistor must be connected to the +Out pin.
2. The trim down resistor must be connected to the –Out pin.
3. Do not trim the converter above maximum trim range
(typically +10%) or the output over voltage protection
circuitry may be activated.
Trim values calculated automatically:
Resistor trim calculators are available onVicor’s
web site at URL: www.vicr.com/tools.html
or by requesting a copy of Vicor’s
Applications Manual on a CD ROM.
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 on
CD ROM also include design tips,
applications circuits, EMC suggestions,
thermal design guidelines and PDF data
sheets for all available Vicor products.

CONTROL FUNCTIONS - PR PIN
Compatible interface architectures include the following:
DC coupled single-wire interface. All PR pins are directly
connected to one another. This interface supports current
sharing but is not fault tolerant. Minus In pins must be tied to
the same electric potential. See Figure 9.
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 cur-
rent share if all PR pins are suitably interfaced.
AC coupled single-wire interface. All PR pins are connected to
a single communication bus through .001µF (500V) capacitors.
This interface supports current sharing and is fault tolerant
except for the communication bus. See Figure 10.
