CUI adds Bus Converter Delivering 720W in a Quarter-Brick Package

March 16, 2014 by Jeff Shepard

CUI Global, Inc. today announced that its wholly owned subsidiary, CUI Inc, has introduced its second-generation high density isolated intermediate bus converter (IBC) family – the NQBS series. The family has been specifically created to address the rising power requirements and efficiency demands in telecom systems and data centers. The NQBS modules are housed in a quarter brick package and deliver a power density of 27.2 W/cm3 (445 W/in3) as well as efficiencies in excess of 96%. These IBC devices incorporate the company's patented Solus® Power Topology, which delivers a greater power density, higher efficiency, faster transient response, and lower EMI in both isolated and non-isolated dc-dc converter designs.

Solus® Power Topology integrates a conventional buck converter into a SEPIC converter to form a SEPIC-fed buck converter; a single stage topology with one magnetic element, one control switch and two commutation switches that are optimally controlled by pulse-width modulation (pwm). The NQBS series IBC module incorporating the Solus Topology joins the company's recent high performance non-isolated point of load product introductions.

"As more of the world comes online, designers of next-generation networking equipment are being asked to manage significantly higher power demands in the same space," said Matt McKenzie, CUI's president. "Maximizing efficiency and power density at every point in the power architecture has, therefore, become critical. When combined into a distributed power system, we believe our Novum Advanced Power portfolio provides an extremely compelling answer to the growing power challenges in today's networking designs," concluded McKenzie.

CUI Global's president & CEO, William Clough commented, "This is the second significant product announcement in the last month to come out of CUI Inc's Novum Advanced Power Group. Their team of talented engineers continues to push intelligent power management designs ahead of the curve in this large and rapidly evolving market."
