Output Connections and Considerations
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. If an external
remote-sense circuit is used, the remote-sense leads must be

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
two 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, 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.
Primary Auxiliary Supply
During normal operation only, the PC Pin can source 5.7V
@ 1.5mA. In the example shown in Figure 4, PC powers a

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.
