The DC761A-B application field and working principle are evaluated for the purpose of providing users with a comprehensive understanding of this product. The DC761A-B is categorized as an Evaluation Board - DC/DC & AC/DC (Off-Line) SMPS, and is designed for the evaluation of Switch Mode Power Supplies (SMPS) with AC/DC or DC/DC power requirements. The board is able to provide certain features, such as a softstart feature for reducing inrush current, over-voltage protection, clock synchronization, and power conversion speed.The main components of the DC761A-B evaluation board include a DC-DC or AC-DC controller, an output transformer, MOSFETs, capacitors, and other components as listed in the datasheet. In order for the board to work, users will need to connect the output transformer, the primary side of the controller, the output load, and the enable pin of the controller. This is done by connecting the board’s component pins to a user’s desired external components.The working principle of the DC761A-B is based upon the inherent switching nature of SMPS technology. The board’s output transformer produces a high frequency alternating current signal that is fed to the primary side of the controller. The controller then processes the signal in order to regulate the output voltage according to the input voltage given to the controller. This is done by opening and closing the switches of the controller in an on-off fashion.The main use for the DC761A-B is the evaluation of the general performance of a DC/DC or AC/DC SMPS. Users are able to measure the input and output voltage as well as the input and output ripple, and can also evaluate the performance under certain load conditions. Additionally, with the use of the overvoltage protection feature, users can make sure their application will not be damaged due to a sudden surge of voltage.The DC761A-B evaluation board is a cost-effective, easy to use solution for the evaluation of SMPS designs. It provides users with an easy way to evaluate the performance of their power supplies and can be used for applications where the input voltage is either AC or DC. Furthermore, the board’s softstart feature, over protection, and clock synchronization add a layer of protection to users’ applications and can help to prevent damage caused by sudden voltage surges.
