DC-DC converters are electronic circuits that convert a direct current (DC) to a different direct current at a different voltage. They are powered by direct current sources like car batteries or solar cells and are used in modern electronic devices such as cellular phones, laptops, and MP3 players. The basic structure of a DC-DC converter includes two or more semiconductor switches, such as transistors, thyristors, or SCR’s, connected in parallel, as well as a step-down transformer (or a DC-DC buck converter).

SQE48T20050-PGB0G is a specific type of DC-DC converter manufactured by Sumitomo Electric Industries, Ltd. This unit is designed to provide a low input/high output voltage transformation and is suitable for applications such as instrumentation, computers, industrial controllers, video/audio equipment, and communication systems.
