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 ...

MOSFETs are small but powerful components that act as ultra-fast switches in electronic circuits. In this video, you’ll learn ...

Two omnipolar magnetic switches from Littelfuse combine tunneling magnetoresistance (TMR) and CMOS technologies in a compact LGA4 package.

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 ...

Switching has almost always meant “hard" switching, which is simple but comes with all kinds of electrical and thermal ...

Validation of a 0.5-MW system for the U.S. Navy proves Menlo Micro’s scalable power-switching platform for defense, data center, and industrial markets This milestone marks a first for the MEMS ...

Learn more about integrating GaN power FETs into switch-mode power supplies and what you must change when upgrading from silicon MOSFETs. The power-handling properties of GaN. The unique challenges of ...

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, ...
