28 V Input  
SECONDARY CONTROL - SC PIN  
PARALLEL BUS - PR PIN  
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 0.001 µF (500 V)  
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.

Trim Down  
1. This converter is not a constant power device – it has a  
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.

* See Maxi, Mini, Micro Design Guide.  
Trim Up  
1. The converter is rated for a maximum delivered power. To  
ensure that maximum rated power is not exceeded, reduce  
maximum output current by the same percentage increase in  
output voltage.
