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. xppower.com Input Characteristics Characteristic Input Voltage Transient Input Voltage Range UVLO Turn On UVLO Turn Off Minimum 10 10 9.5 Typical 28 Maximum 40 50 8.8 Units VDC VDC VDC VDC Notes & Conditions Continuous 50 VDC for 100 ms See models and ratings table, typical and measured at 28 VDC input Input Current Inhibited Input Current Inrush Current Input Reverse Voltage Protection 4 40 mA A Peak value External components required Output Characteristics Characteristic Output Voltage Output Voltage Adjustment Output Current Output Set Tolerance Minimum Load Single O/P Ripple & Noise Vout ≤5V Vout >5V Overvoltage Protection Overload Protection Short Circuit Protection Overtemperature Protection Minimum Typical -20 +10 ±1.5 0 50 100 140 140 120 110 Remote Sense Load Regulation Maximum Single O/P Line Regulation Maximum Output Capacitance Start Up Time Start Up Rise Time Temperature Coefficient Notes & Conditions See models and ratings table for details -10% min voltage trim for 3V3 version See models and ratings table for details No minimum load required mV Pk-pk at 100% load and 20 MHz bandwidth % % Vout nominal At Vin nominal, see figure 3 Output turns off until the short is removed Baseplate Temperature Total voltage compensation.

Synchronization Diagram 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. +Vin +Vout Remote On/Off Thermal Warning (Tw) -Vin Load -Vout Figure 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.

If two modules or more are synchronized, they will run at the highest frequency. Connect synchronization pins directly together. Sync Converter 1 Load Sync Converter 2 Load Figure 1. Synchronization Diagram 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. +Vin +Vout Remote On/Off Thermal Warning (Tw) -Vin Load -Vout Figure 2. Thermal Shutdown Connection Diagram Overload Protection 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 and the unit will enter trip and restart mode. Automatic recovery when overload is removed. 4 xppower.com Remote Sensing - Single Output Models Only +Vout R lead +Sense Load Power Supply -Sense R lead -Vout Figure 4. Remote Sense Connection Diagram 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.
