BM2P249TF-EVK-001

The BM2P249TF-EVK-001 evaluation board is a development and testing aid used in power supply design applications such as DC/DC and AC/DC (off-line) switch-mode power supplies (SMPS). The board is designed by Power Integrations and provides a complete overview of the performance characteristics of the reference design, in an easy-to-use package.

The BM2P249TF-EVK-001 evaluation board includes a 5-5-3 universal input range, incorporating both AC and DC inputs. This board has an Integrated circuit (IC) with the SIKO isolated flyback controller IC topology built-in, allowing few external components for a basic functional solution. The outputs range from a single output version, with values ranging from 5 V/100 mA up to a 5 V/2 A version.

The board incorporates two key features: Fast Transient Capture (FTC) and Load Regulation. Fast Transient Capture (FTC) allows the board to rapidly capture and analyze the load transient response of the SMPS. Load regulation is the ability to control the output voltage, allowing for precise voltage adjustment in the most demanding of applications.

The evaluation boards come in two different models: the BM2P249TF-EVK-001 and the BM2P249TF-EVK-011. The BM2P249TF-EVK-001 is the basic evaluation board and includes the SIKO Flyback controller IC and power stage components. The BM2P249TF-EVK-011 version is the fully featured version and includes the SIKO Flyback controller IC, power stage components, plus a full suite of support components including Snubber diodes, Snubber capacitors, Inductors, and additional resistors.

The board features an on-board USB-JTAG programming interface for easy programming and control, multiple test points for external instruments to monitor various signals, and an overvoltage lockout protection. The board also has an integrated load protection circuitry, protecting both the SIKO Flyback controller IC as well as the external MOSFETs.

To ensure that the board is being used correctly, it is important to read the user manual carefully before operation. This includes directions for setting up the board correctly, tips on optimal usage, and an overview of the built-in features and protection circuitries.

In conclusion, the BM2P249TF-EVK-001 Evaluation Board is an invaluable development and testing aid for designing DC/DC and AC/DC (off-line) SMPS systems. With its comprehensive set of features and easy to use design, this board provides an ideal platform for quickly testing and refining SMPS designs, making it an excellent tool for professionals who need to get to market fast.
