This article is part of The engineer’s complete guide to capacitors. If you’re unsure of what type of capacitor is best for your circuit, read How to choose the right capacitor for any application.

Switching power supplies are used in almost every end-equipment that needs a long battery life, low heat genera­tion, or to meet ENERGY STAR ® guidelines. When designing a switching power supply, it ...

Capacitors are a crucial component of any electrical circuit, and every engineer should know how they work and when to use them. But as with every electronic component, there’s a lot to understand ...

All buck converters need capacitors on the input. Actually, in a perfect world, if the supply had zero output impedance and infinite current capacity and the tracks had zero resistance or inductance, ...
