The Brick Business Unit of Vicor Corporation has announced the addition of eight wide-input Micro DC-DC converters to the 28VDC input family. These models have nominal output voltages ranging from 3.3 to 48VDC and a maximum power of 100W (50W at 3.3Vout and 5Vout, and 100W at 12, 15, 24, 28, 36 and 48Vout). They  meet the European standard for electronic equipment used in rolling stock; EN50155, and can be used in a variety of vehicle or man-portable applications including lighting, communications, portable test equipment, display and control systems. With efficiency up to 82%, the converters operate from 28V nominal input with an input range of 9 to 36V. These models are available in four environmental grades – with operating temperatures as low as -55°C – with six pin options and three baseplate options. These compact modules are also available in RoHS-compliant variants, and measure a compact 57.9 x 36.8 x 12.7mm (2.28 x 1.45 x 0.5in), with a trim range of 10% to 110% of nominal output voltage.
