Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS

DC1213A is an evaluation board which allows users to design, test, and evaluate their own off-line switching power supplies. It is designed to work with any voltage higher than 110 VAC to achieve a secure, reliable performance. Users can configure DC1213A to match the desired specifications such as input voltage, output voltage, and current for their own designs as needed.

The DC1213A board features a built-in "Standard Boost Mode" power supply controller on board, which provides a constant on state current and allows the user to reduce the size and cost of the design. DC1213A is a universal switching power supply board, which supports multiple standards, such as global CEC, DOE, and CSA. In addition, DC1213A also supports multiple control options such as cycle-by-cycle current control and fixed or variable frequency control.

In addition to the boost mode operation, DC1213A has a flyback operation with a peak current mode control. The peak current mode control will ensure stable operation over wide line and load conditions. The user has the ability to set the peak current minimum limit and the protection control circuitry will shut off the power switch when the peak current reaches this level. This will create a robust and safe design for the user.

The DC1213A board also includes an isolated feedback and control section, which eliminate potential ground loops in the system. This is done by providing a built-in isolated feedback, which is de-coupled from the input and output sides of the power supply. The DC1213A also includes the necessary circuitry for the user’s own current limit, thermal shutdown, and external synchronization. DC1213A even includes an optional current- sense amplifier for a more accurate load current monitoring.

In addition to the built-in features, DC1213A also includes the necessary features to allow the user to design and build their own power supply. There are two sets of 4-run terminals for the output connections which can easily be used for connecting the transformer and switches. The DC1213A also includes commonly used components on the board for connecting the input, output, and control signals. The built-in components on the DC1213A offer the user an easy way to build and evaluate their own power supply design.

DC1213A is an ideal switch mode power supply board for both beginners and experienced users. With the features described above, DC1213A will prove to be a valuable tool for users to design, test, and evaluate their own switch mode power supply.
