Some time ago we had introduced you to the Torpedo switching power supply, a particular kind of DC/DC power supply called SEPIC capable of supplying 5 V from several external supply sources, such as an external voltage between around 3.5 and 20 V, the 5 V coming from a USB connector or the 3…
The SEPIC configuration, a very useful one, is used in modern converters for mixed supply systems. Thanks to the availability of an always growing number of specialized integrated circuits that realize – with the help of very few external components – some complete and valid voltage regulators, today the switching technology is the most…
