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 ...

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 ...

It is a common belief that multi-layer ceramic capacitors (MLCCs) or DC power supply circuits cause audible noise, but that’s not true. The noise is generated by the PCB, not by the components. The ...

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 ...

For the PDF version of this article, click here. The goal of this project was to design and build an efficient power supply system whose output voltage (V OUT) could be accurately set to a digitally ...

If you work on simple digital projects, just about any bench supply will offer the voltage and current you’re looking for.

ABLIC has released the S-19560B Series, a power management IC for automotive camera modules that supports 4.0 V to 16 V input and provides three regulated outputs. The device integrates two step-down ...

You may have seen the Ruideng range of programmable power supply modules from China: small and relatively inexpensive switch-mode buck converters, with microprocessor control and a front panel ...
