SECONDARY CONTROL - SC PIN
Output Voltage Programming
The output voltage of the converter can be adjusted or
programmed via fixed resistors, potentiometers or voltage
DACs. See Figure 8.
PARALLEL BUS - PR PIN
Parallel Operation
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:
to a single communication bus through 0 . 001 μ F (500 V)

AC coupled single-wire interface. All PR pins are connected
capacitors. This interface supports current sharing and is fault

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.

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

3. Do not trim the converter above maximum trim range
(typically +10%) or the output over voltage protection
circuitry may be activated.
