Thermal Warning Signal
The MTC35 & 50 are COTS DC-DC converters developed specifically for the defense and avionics market. These products have full military
specifications while offering the short lead-times and cost benefits of a COTS component.
The products offer excellent size, efficiency and EMC performance and the input range is designed to provide short term operation over 10–50 VDC to
enable the converter to work at full power through the dips and surges commonly seen in vehicle and aircraft applications.
Comprehensive control functions such as voltage trim, remote sense, remote on/off and frequency synchronization to an external source are standard
features. The MTC35 & 50 contain an over temperature warning signal that gives user control over the temperature shutdown function of the converter.
When used in conjunction with the DSF and FSO input filter module the MTC35 & 50 are compliant to MIL-STD 461F CE/CS,
MIL-STD1275A-D and MIL-STD 704B-F as well as DEF-STAN-59-411 and DEF-STAN 61-5 part 6 issue 5.

Synchronization
The internal switching frequency can be synchronized to an external source within the range 450 to 550 kHz. If two modules or more are
synchronized, they will run at the highest frequency. Connect synchronization pins directly together.

Thermal Warning
The thermal warning pin is an open collector signal with it’s emitter connected to -Vin. Transistor is off under normal conditions and is turned on when
trip threshold is exceeded typically 105 ˚C. The output of the module can be optionally turned off under a high temperature condition by connecting the
Thermal Warning (TW) pin directly to the Remote On/Off pin (Thermal Shutdown). The output will recover automatically when the case temperature is
reduced.

Figure 3. Over current Profile
After reaching the limit between 110% to 140% of Inom (current or power limit point), the output voltage will reduce down to 40-50% of nominal below
which the unit will enter trip and restart mode. Automatic recovery when overload is removed.

Notes.
1. To use the remote sense connect +Sense pin to +Vout and ꢀSense pin to ꢀVout.
2. When remote sense is not in use leave pins not connected or connected locally to Vout.
Output Voltage Adjustment
To trim the output voltage of the single output versions up or down, connect the trim resistor either between the trim pin and +sense for trimming-up or
between trim pin and -sense for trimming-down. To trim the output voltage of the dual output versions up or down, connect the trim resistor either
between the trim pin and +Vout for trimming up or between trim pin and -Vout for trimming down. The trimming output voltage range is 10% on 3V3
output voltage and -20% to +10% rated output voltage on others. See diagram & table below.

The MTC75 & 150 are COTS DC-DC converters developed specifically for the defense and avionics market. These products have full military
specifications while offering the short lead-times and cost benefits of a COTS component.
The products offer excellent size, efficiency and EMC performance and the input range is designed to provide short term operation over 10–50 VDC to
enable the converter to work at full power through the dips and surges commonly seen in vehicle and aircraft applications.
Comprehensive control functions such as voltage trim, remote sense, remote on/off and frequency synchronization to an external source are standard
features. The MTC75 & 150 contain an over temperature warning signal that gives user control over the temperature shutdown function of the
converter.
When used in conjunction with the DSF and FSO input filter module the MTC75 & 150 are compliant to MIL-STD 461F CE/CS,
MIL-STD1275A-D and MIL-STD 704B-F as well as DEF-STAN-59-411 and DEF-STAN 61-5 part 6 issue 5.

The internal switching frequency can be synchronized to an external source within the range ±50 to 550 kHz. If two modules or more are

Thermal Warning
The thermal warning pin is an open collector signal with it’s emitter connected to -Vin. Transistor is off under normal conditions and is turned on when
trip threshold is exceeded typically 105 ˚C. The output of the module can be optionally turned off under a high temperature condition by connecting the
Thermal Warning (TW) pin directly to the Remote On/Off pin (Thermal Shutdown). The output will recover automatically when the case temperature is
reduced.

Output Voltage Adjustment
To trim the output voltage of the single output versions up or down, connect the trim resistor either between the trim pin and +sense for trimming-up or
between trim pin and -sense for trimming-down. To trim the output voltage of the dual output versions up or down, connect the trim resistor either
between the trim pin and +Vout for trimming up or between trim pin and -Vout for trimming down. The trimming output voltage range is 10% on 3V3
output voltage and -20% to +10% rated output voltage on others. See diagram & table below.

Derating Curves
The operating case temperature range of MTC75 & 150 series is -40 ˚C to +100 ˚C (start up at -55 ˚C). When operating the MTC series, proper derating
or conduction cooling is required. The maximum case temperature under any operating condition should not exceed 100 ˚C.

Example
The minimum airflow required for part number MTC7528S12 operating at nominal line, an output current of 6.25 A and a maximum ambient
temperature of 40 ˚C can be determined using the formula below
Solution:

Given: Pd = 14.29 W and Ta = 40 ˚C
Check above Power derating curve: Minimum airlfow = 400 LFM (2.0 m/s)
Verification:
Maximum temperature rise ∆T = Pd x Rca = 14.29 x 3.64 = 52 ˚C
Maximum case temperature:
Where:
Tc = Ta + ∆T = 92 °C
Rca is thermal resistance from case to ambient.
