This is a DC Transformer Master article - many features are customizable. This master DCDC converter briefly outlines the rough specifications. Its independent current and voltage control allows the Master 25X to be used as a battery charger or as a charge converter with quasi CC-CV charging characteristics as a battery charger with a DC input. Possible applications: battery-powered or supercapacitor-powered systems, systems with a large DC voltage swing, e.g. from 6V to 48V to feed back into the 48V board network (boosters). A customized DC-DC converter for 48V voltage stabilization, for 24V voltage stabilization, for 12V voltage stabilization, ...
