It’s a story we’ve told dozens of times already. The cost to manufacture a handful of circuit boards has fallen drastically over the last decade and a half, which has allowed some interesting ...

PCB inductors are a subject that has appeared here at Hackaday many times, perhaps most notably in the electromagnetic exploits of [Carl Bugeja]. But there is still much to be learned in the creation ...

A good switching power supply requires a good printed circuit board. In order to make an efficient one, the PCB designer should understand the phenomenon behind the operation of the typical switching ...

We report a fabrication technology for 3D air-core inductors for small footprint and very-high-frequency power conversions. Our process is scalable and highly generic for fabricating inductors with a ...

Semiconductor manufacturers have developed innovative production techniques that enable the integration of multiple components and a dc-dc converter IC die into a single module. Producing such a dc-dc ...

The ability to operate at up to 25A is made possible by a new, thermally enhanced 5 x 6 mm PQFN (Power Quad Flat No-Lead) package using a copper clip, as shown in Fig. 1. Fig. 1. Fabrication of the ...
