The addition of eight new wide-input 28V quarter-brick Micro DC-DC converters from Vicor provide more choice for power designers in commercial, industrial or MIL-COTS applications.

With efficiency up to 82%, these new converters operate from 28V nominal input with an input range of 9 to 36V. They offer nominal output voltages from 3.3 to 48VDC with a wide nominal output voltage trim range of 10% to 110%. The maximum power rating for the 12 to 48V output modules is 100W, whilst the 3.3V and 5.0V versions are rated for 50W maximum power. Four environmental grades support operation at temperatures down to -55°C, whilst the choice of six pin styles, and three baseplates, provides flexible mounting options. These compact modules are available with gold/copper terminations for RoHS-compliant designs, or with tin/lead terminations for RoHS-exempt applications.

Designed for 12V or 24V commercial or MIL-COTS vehicle battery systems, these DC-DC converters can also be used for man-portable applications such as lighting, communications and portable test equipment as well as display and control systems.

A new educational initiative from Vicor gives power design engineers expert support throughout the power system design process from selecting the optimum architecture to meeting EMI regulations.

The first free PowerTechtorials interactive CD includes one-on-one video tutorials with technical presentations and lab demos. The tutorials address everyday technical issues and answer real-world questions on power-system design topics. Web links to product datasheets, technical articles, application notes and more, make choosing the right topology and power module fast and faultless.

PowerTechtorials CD Volume 1 presents videos on techniques for improving output filtering and input overvoltage protection as well as an overview of Vicor DC-DC converter theory. The second PowerTechtorials CD will be published in the second half of the year and include expert advice on improving EMI filtering and thermal management. Further free educational initiatives from Vicor will include webcasts on EMI filtering and other power design topics.

Vicor VE-200 DC-DC converters are being used at the heart of the power block for a major new on-board CCTV system, installed by Portugal Rail, to increase passenger safety.

The power modules are one of the most crucial components in the main ‘CCTV System for Transportation Systems and Passenger Transportation’ project. The design needed a nominal input of 72VDC, with outputs to 12VDC and 24VDC, both supplying 100W.

Using the 12V VE-241-CW and 24V VE-243-CU DC-DC converters, and working with Vicor distributor Arrow Iberia, the design team followed Vicor guidelines to create an active filter circuit for EMC filtering and input protection. This shielded the system from damage caused by fast transients and surges. The finished power block passed all the tests for reliable operation across a wide temperature range, and in the presence of transients, surges, shock and vibration, allowing it to gain EN50155 certification.
