How to Choose a Switching Power Supply For Your Next Project

Sometimes selecting a switching mode power supply for your project is no easy task, but information provided here would get you started. In this article I will tell you about most important things you need to know about switching mode power supplies (SMPS) (or just Switching Power Supplies – SPS). So, let’s begin!

Cheap DC-DC and AC-DC Converters Automated Efficiency Measurement Method

Well, the thing is – now you can easily buy DC-DC converter chips for less than $0.2 in relatively small quantities. And because of that, and because different voltages required by microcontrollers and other chips – you can find yourself putting two or even more DC-DC converters on a single board.

PWM Generator Project (part1)

Very often when designing some stuff I need a square wave signal generator with variable pulse width and frequency to control power MOSFETS. You can use such a tool when designing DC-DC converter or switch-mode power supply, you can use it to emulate PWM from microcontroller when developing some new embedded design, or maybe you …
