It is less cumbersome than an AC transformer or inductor. This can be something as simple as a 555 timer or even a dedicated SMPS IC like the famous MC34063A IC.Īs you can see, there are only a few parts required to make a boost converter. Also needed is a source of a periodic square wave. All it consists of is an inductor, a semiconductor switch (these days it’s a MOSFET, since you can get really nice ones these days), a diode, and a capacitor. As the name suggests, it takes an input voltage and boosts or increases it. They’re called switch mode because there’s usually a semiconductor switch that turns on and off very rapidly.Ī boost converter is one of the simplest types of switch mode converter. Anything that has too many steps is inefficient this is a good life lesson too.Įnter the world of switch mode DC-DC converters! It is possible to convert one DC voltage to another, however, the methods are slightly on the clever side.Īnd no, it does not involve the conversion of DC to AC and back again. That too, in most cases, the current draw is quite decent.Įventually, we ask ourselves the question, is it possible to convert one DC voltage to another? Or maybe we have a 3.3V supply when our chip needs 5V. We need 12 volts but have only a 9-volt battery. We’ve all come across pesky situations where we need a slightly higher voltage than our power supplies can provide.
