  • Frequency Synchronization The MTC05 is a COTS DC-DC converter developed specifically for the defense and avionics market. This product has a full military specification while offering the short lead-times and cost benefits of a COTS component. The MTC05 uses a forward converter design switching at 450 kHz giving excellent size, efficiency and EMC performance. 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. A soft start circuit provides well-controlled outputs with no overshoot. Comprehensive control functions such as voltage trim, remote sense, inhibit and frequency synchronization to an external source are standard features. When used in conjunction with the MTF input filter module the MTC05 complies to MIL-STD 461E/F CE/CS MIL-STD 1275A-D and MIL-STD 704A.

xppow er.com Synchronization The recommended level for the synchronization is a TTL signal but slightly higher levels may be used without a problem. However the maximum positive level should not exceed 5V. The ideal synchronization signal is a pulse of minimum of 200ns and low and high levels of <0.8V and 4V to 5V respectively within a frequency range of 450kHz to 500kHz. The trigger is the falling edge of the signal and the impedance of the sync pin is >10kohm. If the synchronization feature is not required the sync pin is recommended to be connected to ground to prevent any abnormal interference.

The input range is designed to provide short term operation over 10 – 50 VD C to enable the converter to w ork at full pow er through the dips and surges com m only seen in vehicle and aircraft applications. A soft start circuit provides w ell-controlled outputs w ith no overshoot. C om prehensive control functions such as voltage trim , rem ote sense, inhibit and frequency synchronization to an external source are standard features. The M TC 3 0 contains an over tem perature w arning signal (battle m ode) that gives user control over the tem perature shutdow n function of the converter. The internal filtering m eets the conducted em ission requirem ents of M IL-STD 4 6 1E/F w ithout external com ponents. W hen used in conjunction w ith the M TF input filter m odule the M TC 3 0 com plies to M IL-STD 4 6 1E/F C E/C S, M IL-STD 1275A-D and M IL-STD 70 4 A-F.

P O W E R I N G T H E W O R L D ’ S C R I T I C A L S Y S T E M S 4 xppow er.com Synchronization The recommended level for the synchronization is a TTL signal but slightly higher levels may be used without a problem. However the maximum positive level should not exceed 5V. The ideal synchronization signal is a pulse of minimum of 200ns and low and high levels of <0.8V and 4V to 5V respectively within a frequency range of 400kHz to 500kHz. The trigger is the falling edge of the signal and the impedance of the sync pin is >10kohm. If the synchronization feature is not required the sync pin is recommended to be connected to ground to prevent any abnormal interference. Therm al W arning (TW ) As it can be seen from the block diagram above the thermal warning pin is an open collector output. It can be used for an over-temperature protection up to 107 °C by connecting it to the inhibit pin. When the base-plate temperature of the converter is between 102 °C and 107 °C the transistor will be switched on and will pull the inhibit pin to ground. If the TW pin is not connected the converter will run without over-temperature protection. This could be used during battle when the part will operate until destroy itself due to overheating.
