A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (load). It is a class of switched-mode power supply (SMPS) typically containing at least two semiconductors (a diode and a transistor,... view more

Usually, each time I have a project with a small battery that I also want to charge, I use a small charging module with USB connector. But then, all the other digital components usually work at 5V, but the battery is 3.7V. So, for that I add another small module, a boost converter to give me 5V. ... view more

If you ever opened a power supply of some sort, you might have seen a special component. That is a transformer but used in a FLYBACK configuration or sometimes called a coupled inductor. You will also notice that the transformer doesn’t have just one input and one output as common transformers ... view more
