DC2229A-A evaluation boards are versatile, easy-to-use development system for test and optimization of dc/dc and ac/dc (off-line) switch-mode power supplies (SMPS). The system is designed to address a variety of applications, ranging from home and office automation, industrial, motor control, automotive, lighting and other power supply-related applications.

DC2229A-A feature commonly used, proven power supply configurations, flexible operation choices and user-friendly tools, making it easy to develop reliable and efficient power supplies. The evaluation board contains an advanced power supply controller and is outfitted with two different magnetic buildings: a flyback transformer and an LLC transformer.

The functioning principle of DC2229A-A is based on a topology of a synchronous buck regulator, where the output voltage is regulated by varying the duty cycle. The system is designed to be used for the development and testing of both linear and switch-mode power supply topologies. With its wide range of power supply configurations, it can be used for both current-mode and voltage-mode control. For voltage-mode control, the system includes an active-clamp-reset circuitry to reduce switching losses, and for current-mode control, it includes an active-clamp-reset feedback loop to reduce output noise.

DC2229A-A evaluation boards also provide advanced features such as an integrated digital potentiometer interface, which offers a wide range of input voltage ranges, output voltage ranges, and switching frequencies, plus a power-factor-correction feature to improve the overall system efficiency. Additionally, they offer a user-friendly graphical interface for setting parameters, including output voltage, power supply current limits, frequency synchronization and ramping, over-voltage protection, temperature monitoring, fault logging and real-time monitoring.

In summary, DC2229A-A evaluation boards are ideal for customers and engineers who need to rapidly develop off-line switch-mode power supplies (SMPS) for a wide variety of applications. With advanced features and flexibility, DC2229A-A can be used to develop reliable and efficient power supplies.
