DESCRIPTION
(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.
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 temper-
ature range, –55°C to +125°C, makes the MOR Series an ideal
choice for military, aerospace, space, and other high reliability appli-
cations. In compliance with MIL-STD-704D, the converters will with-
stand 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.
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.
The MOR Series converters incorporate a single-ended forward
topology which uses a constant frequency Pulse Width Modulator

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 overshhoot.

Interpoint’s FME filters are recommended to meet CE03 require-
ments 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.

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 regulation, under the Electrical Characteristics Tables. Dual
outputs may be “stacked” to double the output voltage. See Figure

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 10 for
the proper connections.
