Questions tagged [dc-dc-converter]
DC-DC conversion. Implies conversion of a DC voltage level up or down. DC-DC converter can be isolated or non-isolated. Electronically it can be done by many kinds of circuits, depending upon the application (charge pumps, voltage multipliers, linear voltage regulators, boost/buck switched converters, etc)
