DESCRIPTION
The MTR Series™ of DC/DC converters offers up to 30 watts of
output power from single, dual, or triple output configurations. They
operate over the full military temperature range with up to 84% efficiency. MTR converters are packaged in hermetically sealed metal
cases, making them ideal for use in military, aerospace and other
high reliability applications.
CONVERTER DESIGN
The MTR converters are constant frequency, pulse-width modulated
switching regulators which use a quasi-square wave, single ended,
forward converter design. Tight load regulation is maintained via
wide bandwidth magnetic feedback and, on single output models,
through use of remote sense. On dual output models, the positive
output is independently regulated and the negative output is cross
regulated through the use of tightly coupled magnetics and shunt
regulators. The MTR Series triple output DC/DC converter’s design
includes individual regulators on the auxiliary outputs which provide
for no cross regulation error when a minimum 500 mA load is maintained on the main (+5) output.

Indefinite short circuit protection and overload protection are
provided by a constant current-limit feature. This protective system
senses current in the converter’s secondary stage and limits it to
approximately 115% of the maximum rated output current.
MTR converters are provided with internal filtering capacitors that
help reduce the need for external components in normal operation.
For systems that require compliance with MIL-STD-461C’s CE03
standard, Interpoint offers filter/transient suppression modules
(including the FMC-461, FMD-461 and FM-704A series filters) which
will result in compliance. Contact your Interpoint representative for
further details.
SYNCHRONIZATION
Synchronizing the converter with the system clock allows the
designer to confine switching noise to clock transitions, minimizing
interference and reducing the need for filtering. In sync mode, the
converter will run at any frequency between 500 kHz and 675 kHz.
The sync control operates with a quasi-TTL signal at any duty cycle
between 40% and 60%. The sync pin must be connected to input
common pin when not in use.

Notes for Remote Sense and Trim
1. When trimming output voltage and/or remote sensing, the total output
voltage increase must be less than 0.6 volts at the converters pins to
maintain specified performance.
2. If neither voltage trim nor remote sense will be used, connect pin 3 to
pin 4 and pin 5 to pin 6 or the output voltage will increase by 1.2 volts.
3. CAUTION: The converter will be permanently damaged if the positive
remote sense (pin 6) is shorted to ground. Damage may also result if
the output common or positive output is disconnected from the load with
the remote sense leads connected to the load.

2. Tc = –55°C to +125°C.
3. Up to 90% of the total output current/power is available from either output
providing the positive output is carrying at least 10% of the total output
power.
4. Operation is limited below 16 V (see Figure 22).

Notes
1. Guaranteed, not tested.
2. The sum of the two aux outputs is not to exceed 10 watts. The maximum
load per aux output is 9 watts.
3. To maintain regulation when operating the ±Aux at full load, a minimum load
of 300 mA is required on the main.
4. Measured on each output one at a time with the other outputs at full load.

5. Indefinite short circuit protection not guaranteed above 125°C (case).
6. Response of each output as all outputs are simultaneously transitioned.
Main: 50% - 100% - 50% of main full load
Auxiliaries: 25% - 50% - 25% each, of total auxiliary full load
7. Recovery time is measured from application of the transient to point at
which Vout is within 1% of regulation.
8. Tested on release from inhibit.
