Würth Elektronik wins Product of the Year 2014 award

Würth Elektronik eiSos has been awarded first place in the power supply category of the Product of the Year 2014 awards by readers of the German "Elektronik" magazine. The award was for a power module from the "MagI³C" series.

"Elektronik", a professional magazine published by the Weka group, carries out a reader survey each year to establish a Product of the Year in eleven different categories. This year, Würth Elektronik eiSos was the readers’ favourite in the power supply category. This step-down converter doesn’t require any additional external components. MagI³C stands for "Magnetic Integrated Intelligent IC". The necessary coil and capacitors are already integrated in the chip. The modules have been developed for power supplies to point-of-load DC/DC converters, FPGAs, DSPs, MCUs, MPUs and I/O interfaces.

Modules in the MagI³C-VDRM range with variable output voltage have an input voltage range of
6 V to 42 V and an output voltage range of 0.8 to 24 V. Adjustable switching frequency (200 kHz to 800 kHz) and soft-start provide additional flexibility. These modules offer an outstanding power density with a significantly smaller surface area than that offered by a discrete solution.

Readers were particularly impressed with the well-engineered solution and the integration of several components in one module, ensuring a significant reduction in the development period and the complexity of the circuit design.

This simplification was also praised by Elektronik magazine's expert in power supplies and semiconductors, Dr. Jens Würtenberg: "Power supplies assembly was once a field in which analogue electronics reigned supreme. This specialist field was not limited to the adaptation of power and voltage to the specific data of the next user, but it also made way for creative circuit design with a view to the best possible level of efficiency (....) this has fundamentally changed and digital technology has also become established in this field. Yet the award-winning modules of today are still analogue. Perhaps because the world is still analogue and power supplies for an electronic system without sensors represent the only connection to the physical world."

Würth Elektronik has already won the Product of the Year award twice previously: In 2010 for a multilayer inductor for mobile devices and in 2012 for a coil in the embedded Faltflex process.
