The DC2240A evaluation board allows designers to explore the world of advanced AC/DC high-efficiency power supply design. The board has dual- and single-output versions of DC/DC converters, and can function as a half-bridge or full-bridge rectifier with a inductor or transformer output, respectively. This board is ideal for exploring the various features of advanced DC/DC converters, including EMI/EMC filters, synchronous rectification, active clamping, and current waveform shaping.

The DC2240A evaluation board is equipped with power-conversion components to demonstrate a variety of AC/DC, DC/DC, power factor correction (PFC) and other topologies. Examples of applications that can be studied include power supplies for computer workstations, smart grids, automotive applications, uninterruptible power supplies and LED lighting systems. It can also serve as a reference design to explore the various parameters required for power-conversion solutions.

The DC2240A evaluation board operates in two different modes to provide the user with different power-conversion capabilities. The first mode is known as the isolated mode, which uses a transformer as the output element. This mode is ideal for applications that need full galvanic isolation between the input power and the output circuits. The second mode is the non-isolated or parallel mode, which uses an inductor output element. Both these modes provide different types of power conversion capabilities to the designer.

The DC2240A evaluation board uses advanced control techniques and synchronous rectification to achieve high efficiency, higher power density and low switching loss. The board is equipped with 6 different ICs that provide the necessary control, protection and electrical safety. It also supports the use of additional external components, such as snubber circuits, EMI/EMC filters, and other components required for the application.

The DC2240A evaluation board is also equipped with various diagnostic features, such as current and voltage sensing for the input and output sides of the converter. These features enable the designer to accurately monitor the current and voltage waveforms of the DC/DC converter, and to adjust them according to the requirements of the application. The board also features a circuit breaker, which allows the user to switch between the two different operating modes, and to power off the board in the event of an unexpected emergency.

The DC2240A evaluation board is ideal for exploring the various features of advanced DC/DC converters, as well as for developing reference designs for power-conversion solutions. The board enables designers to explore various topologies, control techniques, and active components in order to develop solutions tailored to their specific application requirements. The board is also equipped with various diagnostic features, to enable the user to monitor the performance of the DC/DC converter, and to ensure the safety of the power-conversion components.
