DESCRIPTION
With up to 120 watts of output power, the MOR Series™ of DC/DC
converters operates from a standard 28 volt bus and offers a wide
input range of 16 to 40 VDC. Full operation over the military temperature range, –55°C to +125°C, makes the MOR Series an ideal
choice for military, aerospace, space, and other high reliability applications. In compliance with MIL-STD-704D, the converters will withstand transients of up to 50 volts for up to 120 milliseconds. Use
Interpoint’s FME28-461 EMI filter to pass MIL-STD-461C, CE03
requirements.
The MOR Series converters incorporate a single-ended forward
topology which uses a constant frequency Pulse Width Modulator
1.7 µΗ
0.5 µΗ
3:2
(PWM) current mode control design and switches at 550 kHz,
nominal. The converters also provide short circuit protection by
restricting the current to 125% of the full load output current. All
models offer two inhibits, one referenced to input common and one
referenced to output common. A remote sense function is available
on single output models.
Using the trim function, the MOR Series can provide any output from
2 to 33 VDC. For example, trimming the two 15 volt outputs of the
15 dual (MOR2815D) to 14 volts, and then stacking the outputs will
provide a 28 volt output. See Figure 11.

Notes:
1. Load fault conditions are measured with a resistive load.
2. Short circuit is measured with a 10 m W (±10%) load.
3. Time to settle to within 1% of Vout.
4. Transition time > 10 µs
5. Output voltage for dual output models is measured at half load.
6. The maximum specification is the total output current/power. Up to 70%
of that total is available from either output provided the other output
maintains a minimum of 15% the total power used.
7. Cross regulation percentages are for the following conditions:
+Po = 30% and –Po = 70%
+Po = 10% and –Po = 50%
+Po = 70% and –Po = 30%
+Po = 50% and –Po = 10%

of that total is available from either output provided the other output

TRIM
Both single and dual output
models include a trim function.
Output voltage can be trimmed
from 60% up to 110% of nominal
V out . When trimming up, do not
exceed the maximum output
power. When trimming down, do
not exceed the maximum output
current.
Vo
Trim Up: α =
, 1.0 ≤ α ≤ 1.1
(
Steady state voltage range is 16 to 40 VDC. Transient range is 40
to 50 V for a maximum of 120 msec. Low voltage lockout prevents
the units from operating below approximately 15.5 VDC input
voltage to keep system current levels smooth, especially during
initialization or re-start operations. All models include a soft-start
function to prevent large current draw and minimize overshoot.
CASE AND EXTERNAL INPUT FILTERS
Internal 500 V capacitors are connected between the case and
input common and between the case and output common. See
Figure 1.
Interpoint’s FME filters are recommended to meet CE03 requirements for reflected input line current. When using an external
input filter it is important that the case of the filter and the case of
the converter be connected through as low as an impedance as
possible. Direct connection of the baseplates to chassis ground is
the best connection. If connected by a single trace, the trace
should be as wide as it is long.

Output
On dual models the positive
output is regulated and the
negative output is transformer
coupled (cross-regulated) to the
positive output. When trimming
the duals, both output voltages
will be adjusted equally.
INHIBIT 1 AND 2
Two inhibit terminals disable switching, resulting in no output and
very low quiescent input current. The two inhibit pins allow access
to an inhibit function on either side of the isolation barrier to help
maintain isolation.

POSITIVE SENSE, SENSE RETURN
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.
SHARE (PARALLELING)
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.
POSITIVE OUTPUT, NEGATIVE OUTPUT
AND OUTPUT COMMON
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
