DESCRIPTION
Converter Design
The Interpoint® MTR Series™ of dc-dc converters offers
up to 30 watts of output power from single or dual output
configurations. MTR (50) models have a wide input voltage
range of 16 to 50 volts. Transient protection of up to 80 volts
input meets the transient requirements of MIL-STD-704A. The
converters operate over the full military temperature range
with up to 81% efficiency. MTR converters are packaged in
hermetically sealed metal cases, making them ideal for use in
military, aerospace and other high reliability applications. The
converters are offered with standard screening, “ES” screening,
or fully compliant to “883” MIL-PRF-38534 Class H screening.
See Table 9 on page 19 and Table 10 on page 20. Standard
microcircuit drawings (SMD) are available refer to Table 3 on
page 6.
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.
Cover Marking
MTR converters are provided with internal filtering capacitors
that help reduce the need for external components in normal
­operation. Use our FMCE-0328™, FMCE-0528™ or FMCE0828™ EMI filter to meet the requirements of MIL-STD-461C
CE03 and CS01 and/or MIL-STD-461D, E and F CE102 and
CS101 levels of conducted emissions.
The cover marking for the MTR 50 has “MTR (50) DC-DC
CONVERTER” below the model number. Refer to Figure 8 on
page 6.

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 140% of the maximum rated output
current.

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 duty cycle
between 40% and 60%. The sync pin must be connected to input
common pin when not in use.
Dynamic Response
The MTR Series feed-forward compensation system provides
excellent dynamic response and noise rejection. Audio rejection
is typically 40 dB. The minimum to maximum step line transition
response is typically less than 4%.
Inhibit Function
MTR Series converters provide an inhibit terminal that can be
used to disable internal switching, resulting in no output voltage
and very low quiescent input current. The converter is inhibited
when the inhibit pin is pulled below 0.8 volts and enabled when
its inhibit pin is left floating. An external inhibit interface should be
capable of pulling the converter’s inhibit pin below 0.8 volts while
sinking the maximum inhibit current and also allowing the inhibit
pin to float high to enable the converter. A voltage should not be
applied to the inhibit pin. The open circuit voltage present on the
inhibit pin is 9 to 11 volts

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. Do not exceed the maximum power.
2. If neither voltage trim nor remote sense will be used, connect pin 3 to pin 4 and pin 5 to pin 6.
3. CAUTION: The converter will be permanently damaged if the remote sense (pin 6) is shorted to
ground. Damage may also result if the output common or positive output is disconnected from
the load when the remote sense leads are connected to the load.
4. When using remote sense for voltage compensation or when using remote sense for trim, the
output will drift over temperature. Contact Applications Engineering for more information at

Notes
1. Guaranteed by qualification test and/or analysis. Not an in-line test.
2. Dual outputs: The over-current limit will trigger when the sum of the currents from both outputs reaches 140% (typical value) of the maximum
rated “total” current of both outputs.
3. An external inhibit interface should be used to pull the inhibit low or leave it floating. The inhibit pin can be left unconnected if not used.

Notes
1. Guaranteed by qualification test and/or analysis. Not an in-line test.
2. Up to 90% of the total output current/power is available from either output
providing the opposite output is carrying at least 10% of the total output power.
3. Effect on negative VOUT from 50%/50% loads to 80%/20% or 20%/80% loads.
4. Effect on negative VOUT from 50%/50% loads to 90%/10% or 10%/90% loads.
See Figure 21 on page 14.
5. Tested with 6800 pF ceramic bypass capacitor connected externally from input
common to case.
www.craneae.com/interpoint
6. Indefinite short circuit protection not guaranteed above 125°C case.
7. Recovery time is measured from application of the transient to point at which
VOUT is within 1% of final value.
8. Tested on release from inhibit.
9. Applies to each output.

1. Standard and ES are non-QML products and may not meet all of the requirements of MIL-PRF-38534.
2. All processes are QML qualified and performed by certified operators.
3. Not required by DLA but performed to assure product quality.
4. Burn-in temperature designed to bring the case temperature to +125°C minimum.
Burn-in is a powered test.
