Output Connections and Considerations
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 25ꢀ 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.
If an external remote sense circuit is used, the remote sense

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.

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.
