XP Power Extends Family of COTS DC-DC Converters for Military Vehicle and Avionic Applications

July 24, 2011 by Jeff Shepard

XP Power introduced the MTC35 and MTC50 series of commercial off the shelf (COTS) 35 and 50W dc-dc converters aimed at a broad range of military vehicle and avionics applications. These extremely robust and encapsulated board mounted modules accommodate a wide input range from 10 to 40Vdc, and can handle transients up to 50Vdc for up to 100ms. Single output modules are available with + 3.3, + 5, + 12, + 15 or + 28Vdc outputs and can be adjusted between -20% and +10% via an external trim pin.

When used in conjunction with XP Power’s DSF, FSO or MTF series of standard EMI filter modules, the MTC series comply with MIL-STD 1275A/B/C/D and MIL-STD 704A standards for surges and transients, and MIL-STD 461E/F for conducted emissions and susceptibility. The units meet the environmental MIL-STD 810F specification that covers shock, vibration, humidity, temperature, salt spray and altitude.

With its baseplate cooling, the converters are suitable for use across a wide range of operating temperature from - 40 to the maximum case temperature of + 100°C. Unit startup is possible from as low as – 55°C.

Control and signal pins provide the ability to inhibit output, provide thermal warning and converter shutdown, and synchronise converter frequency to an external source in the 400 - 500 KHz range. Remote sense compensates for up to a 0.5Vdc drop on the output.

Prices range from $125.00 for the MTC35 to $139.00 for the MTC50 in 500 unit quantities.
