The SMUC0612 is a switched-mode, non galvanic-isolated step-up converter that boosts 6V up to 12V, letting standard 12V equipment run from a 6V source at up to 5A.
The converter uses a switching technique that results in high efficiency, which makes it possible to use a compact housing unit. It is short-circuit protected and current limited, combining high efficiency with high reliability. UK manufactured.
