This is a design idea of high efficiency constant current buck converter for LED lighting using LinkSwitch-TN. It operates in an input voltage ranging from 108 VAC to132 VAC and delivers an output of ...

Due to the widespread availability of highly integrated DC-DC switchmode converter devices, system design engineers no longer have to put much effort into the design of low-power converters for many ...

Specify current ripple ratio to optimize a power supply , relying on extrapolation rather than intuition to choose the right off-the-shelf inductor for your application. An inductor is designed for ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

We all know that the reason the electrical system uses alternating current is because it’s easy to step the voltage up and down using a transformer, a feature which just isn’t possible with a DC ...
