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.
