A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

How to replace MOSFETs with load switches, and the impact of on-resistance. Swapping out diodes with ideal diodes, and the use of ideal-diode controllers. Why replacing fuses and resettable fuses with ...

A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader ...

Hybrid Silicon/Silicon Carbide (Si/SiC) power switches represent an innovative integration of mature silicon-based technology with advanced silicon carbide components. These devices leverage the ...

I'd guess you are looking at a cap failure in the original PSU. 386 era is what, early 90s. 30+ years is a good run. If a replacement PSU doesn't have a switch, you could always hook it to a surge ...

GaN switches promise higher efficiency and higher power density in SMPS. This article discusses the readiness of this technology and its challenges, and provides an outlook on being a replacement for ...
