Vicor Corp. announces new thermal and mechanical mounting options for its IBC050 series of high performance quarter-brick VI BRICK intermediate bus converters (IBCs).
Vicor Corp. announces new thermal and mechanical mounting options for its IBC050 series of high performance quarter-brick VI BRICK intermediate bus converters (IBCs). Now available with an integral baseplate and multiple pin-length options, Vicor’s high-efficiency IBCs offer greater flexibility than previous designs to meet the challenges of high power applications, such as enterprise computing and networking systems.
Utilizing the company's Sine Amplitude Converter topology, the new IBCs deliver peak efficiency of 98%. Vicor’s IBC open-frame package facilitates airflow above and below the modules to minimize the temperature rise of downstream components. For system designers faced with severe thermal challenges or space constraints, the new baseplate option provides the ability to attach a quarter-brick IBC to a heat sink or a cold plate as needed.
Vicor’s quarter-brick and eighth-brick IBCs are pin-compatible with industry standards and available with pin lengths of 0.145, 0.180, and 0.210 in., to accommodate boards of varying thicknesses. Available as drop-in upgrades for industry standard 5:1 and 4:1 fixed ratio converters, Vicor’s IBC050 series of 2.30 x 1.45 x 0.42 in. quarter-brick IBCs provide output power ranging from 600 to 850 W to yield maximum usable power in thermally constrained systems, while freeing up valuable board space for high-value components.
With eighth-brick power levels up to 500 W, smaller IBC modules can replace competitive quarter-bricks, saving space. And, due to their 1 MHz high bandwidth operation, Vicor’s IBCs cut transient response times by a factor of 10, eliminating the need for bulk capacitors across the intermediate bus, saving additional space.
Designers can use the company's new IBC Power Simulation tool, an online simulation capability, to interactively model the electrical and thermal performance of these IBC modules in application-specific operating conditions and thermal environments.
