DC DC Converters: REC20-4812SZ Application Field and Working Principle

DC DC converters are electronic devices that alter the level of electrical power, including voltage and current, of direct current (DC) input power into some other form of direct or alternating current (AC) output power. REC20-4812SZ is a popular DC DC converter frequently applied in a variety of commercial applications, ranging from computers, telecommunications equipment, and consumer electronics to automotive and industrial self-powered applications. It is a compact, low-noise, efficient AC/DC converter, that meets the highest industry safety standards and environmental regulations. In order to select the most suitable models of REC20-4812SZ converter for a specific application, it is important to understand the working principle and its practical applications.

REC20-4812SZ Working Principle

The REC20-4812SZ is a flyback DC DC converter designed to convert energy from an AC line source to a DC load. It typically consists of a transformer, rectifier, fixed output capacitors, and an integrated control circuit. During the “on” time of the cycle, power supplied to the primary of the transformer turns the primary winding on and off, creating a flux field. This flux field cuts through the secondary winding, creating a voltage proportional to the number of turns. The secondary voltage is converted to a DC voltage by the rectifier and the output filter capacitors. The output of the converter is digitally controlled by an internal circuit, which adjusts the pulse width of the transformer’s primary winding. This pulse width adjustment alters the output voltage of the DC converter. The output voltage can also be set using an external resistor connected to the control pins. This feature helps to meet the specific output requirements of each application.
