Primary Control - PC PIN  
Module Enable/Disable  
Module Alarm  
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 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  
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 3 and 5.  
At 5.7V, PC can source up to 1.5mA. In the example shown in  
Figure 4, PC powers a module enabled LED.

Output Voltage Programming  
Parallel Operation  
The output voltage of the converter can be adjusted or  
programmed via fixed resistors, potentiometers or voltage DACs.  
See Figure 8.  
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.  
Compatible interface architectures include the following:  
+OUT  
+S  
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.
