IBCs get new mounting options

Vicor Corp. announces the availability of its IBC050 series quarter-brick VI BRICK intermediate bus converters (IBCs) with different pin-length options and an integral baseplate for more thermal and mechanical mounting option. The IBCs are suited for enterprise computing, networking systems and other high power applications.

The IBCs are said to be 98 percent efficient, thanks to the company's sine amplitude converter topology. Their open-frame package lets air flow above and below the modules to cut temperature increase of downstream components. For system designers faced with severe thermal challenges and/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.

The new pin lengths offered by the IBC are 3.68mm, 4.57mm and 5.33mm, for use on boards of varying thickness, for more design choices.

The IBCs are available as drop-in upgrades for industry standard 5:1 and 4:1 fixed ratio converters, and measure 58.4 x 36.8 x 10.5mm. They offer 600W to 850W maximum usable power in thermally constrained systems, and 1MHz high bandwidth operation. This is said to reduce transient response times by a factor of 10, so that bulk capacitors across the intermediate bus are not needed. Vicor offers designer the online IBC Power Simulation tools they can interactively model the electrical and thermal performance of Vicor's IBC modules in application-specific operating conditions and thermal environments.

Vicor IBC modules are priced at less than $0.09 perW in OEM quantities, and are available now.
