Welcome to AC/DC Power Supplies


Silicon DC/DC convertor

Point of load convertor incorporates PWM controller, power FETs, compensation circuitry and magnetic components in a single, turnkey IC packageUR 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 convertor with an integrated inductor. The company's patented technology provides a powerful point of load (PoL) solution that incorporates a pulsewidth 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 10us.

Programmable oscillators have small benefits
UR has added the ultraminiature EP13E7, EP15E7 and EP16E7 programmable oscillator series to the EPO family of frequency control products from its partner Ecliptek Corporation

In terms of output current, the 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, telecomms and datacomms 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'.
