The MOR converters
can be synchronized to
the system clock by
applying a TTL compat-
ible sync signal to the
Sync In pin. Sync Out
can be used to synchro-
nize other components
to the MOR converter
’
s
switching frequency.

The frequency range for external
synchronization is 525 to 625 kHz.
The requirements for an external
signal are 15% to 50% duty cycle,

Both Sync In and Sync Out are
referenced to input common. Sync
In should be grounded to input
common if not used.

A special remote sensing feature maintains the desired output
voltage at the load. When this feature is not used, connect the
sense lines to their respective output terminals. Remote sensing is
available on single output models only. See Figure 12. Do not
exceed 110% of Vout and maximum output power.

By using the Share pin, up to five single or dual converters may be
paralleled for a total output power of over 500 watts (90% Pout /
converter, max.). The converters will share within 10% of each
other at 25 to 90% rated power. MOR converters feature true n+1
redundancy for reliability in critical applications. See Figure 9 for
the proper connections.
All Positive Outputs and Positive Senses should be connected to
a common point. All Negative Outputs and Sense Returns should
be connected to a common point. The Share pin is referenced to
Sense Return. Leave the share pin floating (unconnected) if not
used.

Output current is limited to 125% of maximum specified current
under short circuit or load fault conditions.
Single output models operate from no load to full load. Dual output
models with balanced loads operate from no load to full load. For
dual models with unbalanced loads, at least 10% of the total output
power must be drawn
from the positive output
at all times, however, the
negative output does not
require a minimum load.
See note 7, cross regula-
tion, under the Electrical
Characteristics Tables.
Dual outputs may be
“
stacked
”
to double the
output voltage.
