The DC903A-B application field and working principle are categorized as Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS. This new product from Digi-Key is one of the most powerful, flexible evaluation boards for testing and evaluating off-line power supply designs. With an integrated DSP controller and motor control capability, the DC903A-B is well suited for use in applications such as motor control, LED lighting, or power conversion.

The DC903A-B offers a flexible platform for evaluation of various off-line power supply schemes. It can be used for tests and evaluation of fly-back, and two switch forward topologies, as well as full-wave or half-wave AC/DC converters. The board offers an adjustable output voltage and current ratings, making it suitable for a wide range of applications.

The DC903A-B evaluation board also provides a convenient way to evaluate power supply designs, eliminating the need for customized testing fixtures and test setups. The board has two main components, a micro-controller and an analog signal chain, which work together to accurately measure the response of the system. The analog signal chain consists of a voltage regulator, a current sensor, a temperature sensor and a voltage comparator. The signal chain is connected directly to the DSP controller’s two IOREF ports, which allows for precise control and measurement of the current flowing through the power supply. Additionally, the board has two AC input voltage terminals, allowing it to function as a regulator for both AC and DC systems.

The DC903A-B offers a wide range of features and capabilities for power supply design and testing. It has two IOREF ports, allowing users to monitor and control the system through the use of an input voltage or a reference voltage. The board also has a low-side output voltage limiting, as well as a power good signal that indicates the output voltage is stable and in the desired range. Other features include a selectable soft start pin and a status pin that provides feedback on the processor’s operation.

Using the DC903A-B evaluation board, it is possible to evaluate the performance and reliability of a wide range of power supplies. In addition, it makes it possible to observe the behavior of a power supply in real-world applications. With its easy-to-use controls and precise measurement capabilities, the DC903A-B makes it easy to optimize power supplies for any design application.
