Power is an uber-popular watercooler topic at any company engineering military electronic applications or systems, being a critical consideration in defense designs. Accordingly, XP Power has incarnated its MTC35 COTS DC/DC converters, specially designed to ease the power and rugged woes.
Power is an uber-popular watercooler topic at any company engineering military electronic applications or systems, being a critical consideration in defense designs. Accordingly, XP Power has incarnated its MTC35 COTS DC/DC converters, specially designed to ease the power and rugged woes that can occur in avionics and military vehicle applications. Case in point: The 35 W converters handle an input range of 10 to 40 VDC and accommodate transients ranging “to 50 VDC for up to 100 ms,” the company reports. Moreover, the encapsulated, board mounted, and robust modules are vended in single-output formats with outputs of +3.3, +5, +12, +15, and +28 VDC; however, single-output modules can be modified with an external trim pin, affording a -20% to +10% adjustment capability.
And these DC/DC converters are rugged galore. In conjunction with the company’s EMI filter modules, the MTC35 series meets MIL-STD-704A and MIL-STD-1275A/B/C/D for transients and surges. Additionally, MIL-STD-810F (rugged environmentals) and MIL-STD-461 E/F (emissions) are met. And the DC/DC converters’ design features baseplate cooling and operation from -40 °C to +100 °C, though the converter can be started at -55 °C. Protection is rendered via signal and control pins, which shut down the converter when needed and give thermal warnings, in addition to inhibiting output and synchronizing external source frequencies ranging from 400-500 KHz. Regarding output, any drops up to 0.5 VDC activate remote sense compensation.
