More Options for 98% Efficient Vicor IBCs

New baseplate and pin-length options extend the versatility of Vicor’s IBC050 series of quarter-brick intermediate bus converters. This opens up more choices for the power system designer working in high power applications such as enterprise computing and networking. You can now opt for not only higher efficiency than competitive bus converters, but also a new baseplate module to support challenging thermal environments. The quarter-brick IBC with baseplate can be attached, as needed to a heat sink or a cold plate. Vicor’s quarter-brick and eighth-brick IBCs are also pin compatible with industry standards and now offered with pin lengths of 0.145, 0.180, and 0.210 inches (3.68, 4.57, and 5.33 millimeters), to accommodate boards of varying thicknesses.

The IBC050 series of 2.30 x 1.45 x 0.42 inch (58.4 x 36.8 x 10.5 mm) quarter-brick IBCs provide output power ranging from 600 to 850W, yield maximum usable power in thermally constrained systems, and free up valuable board space for high-value components. With eighth-brick power levels up to 500W, smaller Vicor IBC modules can replace competitive quarter-bricks and save space. The unique 1 MHz high bandwidth operation of Vicor’s IBCs cuts transient response times by a factor of 10 and eliminates the need for bulk capacitors across the intermediate bus, saving more space.

Check out Vicor’s new  IBC Power Simulation tool, an industry-first online simulation capability, to interactively model the electrical and thermal performance of Vicor’s IBC modules in application-specific operating conditions and thermal environments.
