DC-DC converters are power electronic devices used for achieving efficient electrical energy transfer from a primary source to a secondary load at a required voltage level. The REC3-4815SRWZ/H2/A/M/SMD/CTRL-R is a DC-DC converter manufactured by TDK-Lambda, a leader in the AC-DC and DC-DC power conversion industry. The converter is an isolated dc-dc with wide input voltage range of 18-75V, and a constant current output of 15A. It has an inverter and a DC-DC converter built together as a single unit to offer a high-performance power conversion solution.

The REC3-4815SRWZ/H2/A/M/SMD/CTRL-R is mainly used for applications that require a continuous load with high efficiency, such as automotive, storage, power systems, LED lighting, and IOT devices. It is also a highly functional device that allows for the customization of its power requirements. This device offers selectable features such as output voltage, continuous current, voltage or current monitoring, and control modes.

The isolated converter is also capable of operating in harsh environments due to its high peak power capability and low temperature coefficient output current. The wide input range and adjustable oscillator frequency are desirable features for applications where the input voltage or frequency may vary over time. The converter also includes an internal over-voltage protection function and an output voltage sensing function to ensure a safe shutdown and continuous operation.

The REC3-4815SRWZ/H2/A/M/SMD/CTRL-R DC-DC converter follows a typical flyback topology. The input voltage is first converted in the rectifier section. This voltage is then rectified and applied to the primary winding of a power transformer. The magnetic field generated in the primary winding induces a voltage in the secondary windings. This voltage is further rectified and applied to an output capacitor, which acts as a storage and filter element. The capacitor provides the necessary filtering to achieve a stable output voltage.

The output of the REC3-4815SRWZ/H2/A/M/SMD/CTRL-R is regulated by an on-board current mode control and temperature compensation. The constant current control loop is responsible for adjusting the voltage to regulate the output current. The temperature compensation circuit provides stability to the output voltage by sensing the temperature of the output capacitor and adjusting the switching frequency to maintain a constant output. The converter also includes a power sense element to determine the output power and provide an indication of the total load power consumption.

The REC3-4815SRWZ/H2/A/M/SMD/CTRL-R DC-DC converter offers a high efficiency and reliable power conversion solution for a wide range of applications. Its wide input voltage range and constant current output capability make it an ideal choice for applications that require continuous loads with high efficiency. The on-board temperature compensation and current mode control ensures that the converter operates within its specified parameters and provides the necessary protection features to protect both the input and output from damage. Additionally, its peak power capability and adjustable oscillator frequency allow for use in harsh environments where the input voltage or frequency may vary over time.
