Original Press Release:



DC-DC Converter Designed for Harsh Environments Offers Wide Input Voltage Range



XP Power announces availability of a new series of isolated dc-dc converters. The MQP120 range has been specifically designed for systems that need to be powered from both 12 VDC, 24/28 VDC electrical supplies. The unit is ideally suited to military equipment that might be deployed in both army and commercial vehicles, such as those used for homeland security initiatives. The converter accommodates a wide range of input voltage, from 9 to 40 VDC, and is rated to 120W. Five standard output options are available, giving voltages of 3.3, 5, 12, 15 and 24 VDC.

The MQP120 is fully encapsulated, making the unit resistant to the effects of dust as well as vibration and shock. The unit is compact, being just 3.74 x 0.45 x 2.56 inches (95 x 11.5 x 65 mm), and has a high power density of 26.7 watts per cubic inch. The unit has an operating temperature range of -40 C up to a baseplate temperature of +100 C. An optional heatsink is available to simplify thermal design should cooling via the baseplate prove insufficient.

Typical systems that might use the MQP120 series include communications, sensors and weapons systems on military platforms. An example system is that of an imaging sensor, it needs to be powered from a 28 VDC supply when used in a Humvee but from 12 VDC when used in a commercial SUV.

The MQP120 series can meet military standard, MIL-STD 461 for electro-magnetic immunity and MIL-STD 1275A-D for electrical immunity. An application note is available from XP Power that describes how a design engineer can achieve compliance against these specifications.

The MQP120 is priced at $286 each for orders of 1,000 pieces.
