MOSFETs enhance power density of high-efficiency converters
Very High-Voltage (VHV) super-junction transistors have been announced by STMicroelectronics with the extra advantage of a fast-recovery diode. The latest MDmesh DK5 power MOSFETs help designers maximise the efficiency of various power-conversion topologies including LLC resonant converters with Zero-Voltage Switching (ZVS).

First GaN-on-Silicon Devices on 200-mm Wafers
X-FAB Silicon FoundriesandExagan, a start-up innovator of gallium-nitride (GaN) semiconductor technology enabling smaller and more efficient electrical converters, have demonstrated mass-production capability to manufacture highly efficient high-voltage power devices on 200-mm GaN-on-silicon wafers using X-FAB’s standard CMOS production facility in Dresden, Germany.
Stretchable electronics: everything you need to know
The termStretchable Electronics conceals great diversity. Indeed, it is an umbrella term that refers to a whole host of emerging electronic materials, components and devices that exhibit some degree of mechanical stretchability.Stretchable electronics has been in the making for than a decade, but it up to now it has been mostly a solution looking for a problem.

Compact switch mode power supplies are for smart energy
SMPS are needed for smart energy applications, such as low power lighting controls, audio or thermostat controls and other smart home electronics applications, as well as industrial controls.
GaN transistors save cost and increase efficiency
Power densities are increasing three times or more in many applications as the demand for more power in electronics continues to increase, while the space allowable for power continues to decrease. This increase in power has the collateral effect of producing more heat. More heat traditionally results in the use of higher capacity fans and bigger heat sinks to prevent overheating of the electronic components and system failure.
Engineers: your decisions shape our energy future
First expressed byJeffery Sachs, Director The Earth Institute of Columbia University: "The politicians have done their job; now it’s up to the engineers," was the sentiment that followed thesigning of theParis Agreement, as it isresonating with engineers worldwide.
Innovating efficient delivery of electrical power to modern systems
The power supply used to be an afterthought in electronic systems design. No longer. Today’s systems are complex; they cram more functions into ever-smaller volumes, are increasingly portable and sometimes deployed remotely.
The holy grail of asset tracking tags could now be a reality
Many organisations rely on having the right equipment available in the right place at the right time. Whether it’s sophisticated healthcare apparatus in a hospital, machinery in a manufacturing plant, or portable test kit used by field engineers, being able to track the location and condition of this often high-value gear is essential to the smooth operation of many organisations.
