Enpirion appoints UR as UK sales partner for world's smallest silicon-based power systems

• World's first complete DC-DC converter in an IC package
• Up to 70% reduction in board footprint
• Up to 60% reduction in component count
• Integrated inductor
• Up to 92% peak efficiency
• Simplified design and layout
• Reduced ripple and noise
• Best-in-class transient response

UR Group has been appointed by US-based Enpirion as its UK sales partner. Enpirion produces the world's smallest Power System on Silicon (PSoS) - the first and only all-silicon, switch-mode DC-DC converter with an integrated inductor. The company's patented technology provides a powerful Point of Load (PoL) solution that incorporates a Pulse-Width Modulation (PWM) controller, power FETs, compensation circuitry and magnetic components in a single, turnkey IC package.

The layout and placement of the inductor is one of the most common reasons for power IC-related failures. Enpirion products not only solve this problem but also reduce board footprint by up to 70% and component count by up to 60% as well as reducing noise and ripple associated with switch-mode power conversion. At the same time, they achieve up to 92% peak efficiency, deliver best-in-class transient response and enable a tenfold switching-frequency improvement over solutions that were until now considered state of the art - output supply voltage can be scaled in a blistering 10 microseconds. In terms of output current, t he product line currently ranges from 500mA to 9A and is continuing to expand.

Enpirion's revolutionary technology provides the ideal solution when board space is at a premium and power consumption must be kept to a minimum. It is also ideal for applications where one or more PoL supplies are required to power key circuitry and there is a need to simplify design and manufacturing, reduce development costs and accelerate time-to-market.

Applications include a wide range of high-volume consumer products such as mobile phones, portable game players, set-top boxes, MP3 and personal media players, PDAs, notebooks and PCs. Business and industrial applications include servers, point-of-sale equipment, telecoms and data communications systems, medical equipment and military and aerospace systems.

Joe Matano, Managing Director of UR Group (UK), commented: "Enpirion technology represents the first major innovation in integrated power technology for over a decade. With the need to pack more and more functionality into ever shrinking space, chip-level integration frees up vast amounts of precious real estate. Enpirion solves a multitude of power design problems. The technology is stunning and the benefits are enormous."
