Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

This design was conceived as an add-on for the Variable DC Power Supply, a very successful circuit posted to this website. This simple unit provides a dual-rail variable output ranging from ±2.5V to ...

Every automated test system that tests electronic circuit boards, modules or equipment needs one or more DC power supplies. Specifying the right supply involves more than just finding one that can ...

How many integrated circuits do you need to build up a power supply that’ll convert mains AC into a stable DC voltage? Would you believe, none? We just watched this video by [The Current Source] ...

How semi-automated tools speed up the power-supply design process. The five main steps to take when building a power-supply architecture. How do LTpowerPlanner and LTspice help facilitate the ...

In part 1, we examined the operation of power supply supervisory ICs that can detect when the supply voltage is too low, and ...

Different components affect system accuracy. Shaury Anand, of Texas Instruments, explains how to choose those most suitable for a precision DC power supply design. Test and measurement applications ...

ROHM leverages its LogiCoA technology to control both a power-factor-correction stage and a flyback DC-DC converter stage.

Not sure if this is the right place for this, but it didnt seem like it fit anywhere else so here it goes.<br><br>I'm helping a friend out with an art project, and I need to make a voltage and current ...

There’s no shortage of cheap & cheerful power supplies which you can obtain from a range of online retailers, but with no listed certification worth anything on them calling them ‘dodgy’ is more of a ...

Many applications using miniature brushed DC motors require motors to operate at more than one load point or through specific load cycles. Running a motor at usable load points requires a variable, ...
