Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPSEvaluation boards are used to test and evaluate various types of DC/DC and AC/DC switching power supplies. These boards provide a platform for engineers and researchers to experiment with different design configurations and parameters to determine the optimal performance of a switching power supply. The boards typically come with a range of features, such as adjustable output voltage, built-in measurement and control circuitry, and connectors for interfacing with external devices. They can be used in a variety of applications, including power supply design and development, education, and research.
