What is an SMPS?

Switch mode power supplies are widely used because of the advantages they offer in terms of size, weight, cost, efficiency and overall performance. As a result of their performance, switch mode power supplies are used in all but the most exacting applications to provide an efficient and effective source of power for most forms of electronic systems. Switch mode power supplies have become an accepted part of the electronics scene and are often referred to as switch mode power converters, or just switchers. A switched-mode power supply is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
