Output Connections and Considerations
Remote Sense leads must be protected for conditions such as
lead reversal, noise pickup, open circuit, or excessive output lead
resistance between the sense point and the converters output
terminals. For applications that may draw more than the rated
current, a fast acting electronic circuit breaker must be utilized
to protect the converter. Under no circumstance should the
rated current be exceeded. Utilizing or testing of current limit or
short circuit current will damage the converter. Ensure that the
total output capacitance connected to the converter does not
exceed the limits on Page 16, “Maximum Output Capacitance”,
of the design guide.
The permissible load current must never be exceeded during
normal, abnormal or test conditions. Converters subject to
dynamic loading exceeding 25% of rated current must be
reviewed by Vicor Applications Engineering to ensure that the
converter will operate properly.
Under dynamic load, light load, or no load conditions, the
converter may emit audible noise. Converters that utilize remote
sense may require compensation circuitry to offset the phase
lag caused by the external output leads and load impedance.

48V Input
Primary Control - PC PIN
Module Enable/Disable
Module Alarm
The module may be disabled by pulling PC to 0V (2.3V max)
with respect to the –Input. This may be done with an open
collector transistor, relay, or optocoupler. Converters may be
disabled with a single transistor or relay either directly or via
“OR’ing” diodes for 2 or more converters. See Figure 2.
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,
Primary Auxiliary Supply
Input Undervoltage) 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 3 and 5.
During normal operation only, the PC Pin can source 5.7V
@ 1.5mA. In the example shown in Figure 4, PC powers a
module enabled LED.

48V Input
Compatible interface architectures include the following:
Secondary Control - SC PIN
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 communication bus. Up to three
converters may be paralleled by this method. See Figure 9.
Output Voltage Programming
The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figure 8.
Transformer coupled interface. For paralleling four or more
converters a transformer coupled interface is required, and under
certain conditions a PR buffer circuit.

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.

Designing High-Power Arrays
using Maxi, Mini, Micro
Family DC-DC Converters
The PR pin supports paralleling for increased power with N+1
(N+M) redundancy. Modules of the same input voltage, output
voltage, and power level will current share if all PR pins are
suitably interfaced.

• The +Sense and -Sense leads should be routed in close

Storage
Vicor products, when not installed in customer units, should be stored in ESD safe packaging in accordance with ANSI/ESD S20.20,
“Protection of Electrical and Electronic Parts, Assemblies and Equipment” and should be maintained in a temperature controlled factory/
warehouse environment not exposed to outside elements controlled between the temperature ranges of 15°C and 38°C. Humidity shall not
be condensing, no minimum humidity when stored in an ESD compliant package.
