By Roger Allan, contributing writer There’s good news for power supply system designers. Silicon-based power devices are making performance advances in diode, transistor, and field-effect transistor (FET) functions. But wide-bandgap semiconductor IC technologies like gallium nitride (GaN) and silicon carbide (SiC) are poised to grow rapidly, offering designers greater performance in a smaller package, making […]

GaN components boost power density in supplies
by Eric Persson, Infineon Technologies To understand why gallium-nitride components shrink the size of power supplies, examine how they dissipate energy at high frequencies. Silicon power FETs have come a long way over the past 35 years. Modern high-voltage superjunction FETs have developed over the past 15 years to even exceed what was thought to […]
Evaluation kit for step-down converters
Würth Elektronik eiSos GmbH & Co. KG and Infineon Technologies AG are launching the jointly developed “XMC Digital Power Explorer” evaluation kit. This synchronous step-down converter, which can be assembled with two different control cards (XMC1300 – ARM Cortex-M0 MCU and XMC4200 – ARM Cortex-M4F MCU), makes it easier for developers of analog power supplies […]
Infineon digitizes power for energy-efficient LEDs
Every fifth kilowatt hour of electricity around the world is used for artificial light. LED technology, however, is making significant savings possible. About 13 million tons of CO 2 could be saved in Germany alone, equaling the emission of about seven million cars; in German office buildings, the electricity bill could be reduced by more […]
Infineon Power MOSFETs Make Electrical Appliances More Compact and Durable
DIY tools such as cordless drills and saws have to be handy and durable. Therefore, the electronic components used in the applications need to be space-saving and rugged. Infineon Technologies AG has extended its StrongIRFET™ Power MOSFET family and thereby provides a solution that fulfills both requirements. The Logic Level StrongIRFETs™ can be driven directly […]
