Westcor, a division of Vicor, has added two new members to its LoPAC Series of low-profile AC/DC switchers.
Providing attenuation from 150kHz to 30MHz, the QPI products deliver over 40dB of common-mode and more than 70dB of differential-mode noise attenuation at 500kHz.
All products are pin and footprint compatible with previous versions in compact (25.4 x 25.4 x 5.1mm) surface-mount packages, offering board space savings of 50 to 80% over passive EMI filter solutions.
The QPI-6 meets the specifications for the international 36 to 76V DC telecomms bus, including the 100V, 100ms surge requirement.
Rated at 14A, the unit supports single or multiple DC/DC convertors requiring up to 672W of input power at 48V input.
The QPI-3 and QPI-5 operate over a 10 to 40V DC range to support industrial bus and COTS defence applications.
The QPI-3 and QPI-5 are rated at 7 and 14A, respectively.
The units support single or multiple DC/DC convertors requiring up to 360W of input power at 24V input.
The QPI family requires only 20-30% of the volume and 30-50% of the area of similarly rated passive filters, saving crucial board space.
The surface-mount LGA package is rated for operation over a case temperature range of -40 to +100C with an efficiency of 99%.
Units may be placed in series for even higher attenuation.
The QPI family supports all DC/DC convertors in IT, telecomms, industrial, COTS and other 24 or 48V DC applications requiring efficient filtering in small spaces.
QPIs are packaged in antistatic tubes.
Vicor's comprehensive line of power solutions includes modular, high-density AC/DC and DC/DC modules and accessory components, fully configurable AC/DC and DC/DC power supplies, and complete custom power systems.
