Product Overview
This DC-DC converter module uses
2nd 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
integration results in 1/3 the part count
of a 1st Generation converter.
* Part Numbering
For pin styles see page 6. Slotted baseplate
(style 1) requires no designator. For
threaded baseplate add a "2" to the end of
the part number. For thru-hole, add a "3".
See page 7 for dimensions.
See part numbering chart on this
page for other product grades.

CONTROL FUNCTIONS - PC PIN
Module Enable/Disable
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.
Module Alarm
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.

The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figures 7 and 8.

Trim Down
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 down resistor must be connected to the Sense pin.
Trim Up
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 +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.

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.
OR'ing diodes may be inserted in
series with the +Out pins of each
module to provide
module output fault tolerance.
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:
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.
AC coupled single-wire interface. All PR pins are connected to
a single communication bus through 0.001F (500V)
capacitors. This interface supports current sharing and is fault
tolerant except for the communication bus. See Figure 10.
