The IRAUDPS3, an evaluation board designed by International Rectifier, is a DC/DC & AC/DC (Off-Line) SMPS suitable for a wide range of applications. It is based on the ALD9039 controller and offers great performance and high efficiency, making it suitable for a wide range of applications, including automotive, industrial, medical, and military.

The main features of the IRAUDPS3 board include an integrated active current sharing circuit and a high integration synchronous rectifier. This board also features a Synchronous Rectification Control (SRC) IC, which allows designers to boost the power conversion efficiency of the design by up to 10%. In addition, this board offers support for a wide input voltage range, from 30V to 84V. Moreover, the board enables the user to easily adjust the output voltage, power level, frequency, and the soft-start time.

One of the most attractive features of the IRAUDPS3 board is its simple, easy-to-use design. The board has an intuitive user interface with an embedded web server, which allows users to easily configure their designs. The built-in PC-based software utilities also allow for easy and trouble-free monitoring and analysis of the system status.

The working principle of the IRAUDPS3 board is fairly straightforward. The input voltage is applied to the controller via the SRC IC, which controls the switching of the FETs. These FETs then pass the current through the transformer and rectifiers before the output voltage is applied to the load. The entire process is monitored and controlled by the controller, which helps to ensure a high efficiency and a low noise operation.

In addition, the IRAUDPS3 board also offers an adjustable and variable frequency operation, which allows users to optimize their designs for maximum efficiency. This board also features an embedded PFC controller, which helps reduce input current harmonic distortion and increases the power factor of the design. This board also offers onboard temperature and over-voltage protection to provide enhanced safety and reliability.

Overall, the IRAUDPS3 board is a great solution for creating efficient, reliable, and high-performance switching power supplies for a wide range of applications. It offers an easy-to-use design and intuitive user interface, as well as a wide range of features and options that make it suitable for a wide range of applications. Moreover, the board provides an adjustable and variable frequency operation, as well as an onboard PFC and other protection features. Thanks to these features, the IRAUDPS3 board is an excellent choice for applications that require DC/DC and AC/DC (off-line) SMPS designs.
