Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...

The advantages of a switch-mode power supply (SMPS) are just too great to ignore. Efficiency is the primary benefit, with efficiencies over 90% for many designs. Small size and reasonable cost are ...

[Hesam Moshiri] has built a variable switch-mode power supply over on hackaday.io. When prototyping a new circuit, often the goal is to get a proof-of-concept working as soon as possible to iron ou… ...

For a cost-effective and timesaving approach to design, the EMI characteristics of a switch-mode power supply ... Figure 1 shows the circuit diagram and the PCB layout of a typical power supply.

A 555-timer IC can inexpensively perform PWM. The circuit in Figure 1 shows how to turn a 555 PWM circuit into an switch-mode power supply with only one simple equation. The design uses two 555s. IC 1 ...
