Current Multipliers: The Obvious Choice for Powering AI Processors and Other Demanding Applications

Tom Curatolo, Industrial BU Apps Engineer, Vicor

AI processors can draw up to thousands of amps while operating at voltages well below 1V. This current demand is unprecedented and has turned the power delivery network (PDN) into a major system bottleneck. With every amp pushed through PCB or substrate copper power planes, conductive losses and, thermal m

All Semiconductor Switch Technologies Lead to Rome

Francesco Di Domenico, Principal Application Engineering at Infineon Technologies

Much is made of wide bandgap technologies, especially since GaN and SiC often have a superior performance on paper when compared to classic Si switching devices. These improvements include lower on-resistance and higher thermal conductivity, features that enable improvements in efficiency and operation at higher te

Collaborating for Success in Custom Power Magnetics Designs

Peter F Vaughan, Technical Director, TT Electronics

Despite its long history, the theory of magnetics component design still eludes many engineers, and with some justification; a good description of the effect of a magnetic field is the ‘relativistic correction to the force between charged particles when in motion.’ Many understand the behaviour of magnetics co

Designing a PoE-PD for IoT

Riley Beck, On Semiconductor

Internet-connected devices rely on two core features, communications backhaul and power. With IoT devices, three core concerns regularly crop up: power, communications and security. Wireless technologies, like WiFi, have held the spotlight in the marketplace for years, but they struggle with these three problems. Wi
