For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...

When reaching for a power supply design it’s normal here in 2022 to reach for a switching design. They’re lightweight, very efficient, and often available off-the-shelf at reasonable prices.

However, the three graphs clearly show that the pentagonal coil outperforms its counterparts by a large margin, at least ...

Vishay has introduced an automotive-rated series of positive temperature coefficient (PTC) in-rush current thermistors that can absorb up to 340J, designed for dc link charging and energy discharge ...

Linear power supplies accept AC inputs and provide one or more DC outputs for a wide variety of computer and industrial applications. They use an active element (normally a power transistor) operating ...

DC power supplies are power supplies which produce an output DC voltage. Power supplies are devices that deliver electric power to one or several loads. They generate the output power by converting an ...

A power supply for electronic devices. Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages ...

Field-stripping the Xtreme Gaming card reveals a glorious 12+2 power phase design ... The Xtreme Gaming card does produce a noticeable coil whine on my test bench, but that high-pitched screech ...

The decibel (dB) scale is logarithmic, not linear, increasing by a power of ten with every 10dB, which roughly equates to a doubling in loudness based on average human hearing. Consequently ...
