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 ...

Increasingly, many industrial PCs (IPCs), USB power delivery (PD), and automotive digital video recorders (DVRs) require wide V IN DC/DC converters to cope with a wide range of battery voltage ...

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 ...

The synchronous buck converter is a widely used topology in low-voltage, high-current applications. One common application is a point-of-load (POL) converter that transforms a system bus voltage of 48 ...

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 ...

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 ...
