Cool power

Switch Mode Power Supplies (SMPS) are often too quickly put aside because of their complexity. This article presents an overview to SMPS technology and a brief description of the most widely used topologies, but in a practical way, trying to demystify the topic and encourage the electronics hobbyist to start developing his own 'switchers', or at least know how to choose the right topology for a given application.
