Product Highlights
Vicor’s 2nd Generation DC-DC
converters represent a quantum
leap in the performance and
flexibility of power components.
With advanced power processing,
control, and packaging technologies,
power density has tripled while
reducing the cost per Watt of
processed power. A high level of
silicon integration reduces parts
count to less than a third of
1st Generation converters,

increasing reliability.
Fully encapsulated, Vicor 2nd
Generation modules utilize a
proprietary spin fill process that
assures complete, void free
encapsulation making them
suitable for the most harsh
military environments. Two
military grades (H & M) are
available with temperatures to
-55°C operating and -65°C
storage. H & M-grade modules
have been subjected to the
environmental testing requirements
of MIL-STD-810, MIL-S-901, and
MIL-STD-202 and undergo 100%
environmental stress screening.

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 3.

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
(–Out pin on a micro).
2. The trim-up resistor must be
connected to the +Sense pin.
(+Out pin on a micro).
3. Do not trim the converter above
maximum trim range (typically +10%)
or the output overvoltage protection
circuitry may be activated.
Control Functions - PR Pin
Parallel Operation.
Note:
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
another. This interface supports current
sharing but is not fault tolerant. Minus In
pins must be tied to the same electric
potential. See Figure 6.
Please consult the
appropriate Vicor Design
Guide for additional
information regarding the
use of these products.
AC coupled single-wire interface. All PR
pins are connected to a single communication
bus through 0.001µF (500V) capacitors.
This interface supports current sharing
and is fault tolerant except for the
are suitably interfaced.
Compatible interface architectures include:
DC coupled single-wire interface. All PR
pins are directly connected to one
communication bus. See Figure 7.
