Evaluation Boards - DC/DC & AC/DC (Off-Line) SMPS provide device developers the ability to analyze their circuit boards and subsystems with high accuracy. The DC409A is designed as a universal platform for this type of evaluation boards, which enables device developers to get the power systems performance data they need to evaluate performance and accuracy for their boards. Furthermore, the DC409A works with external components, such as inductors, rams, converters, and other circuitry, which allows device developers to test the full system in a single package.

The DC409A can be used to accurately evaluate switch mode power systems, which includes High Efficiency DC/DC Converters, AC/DC Converters, and Line Regulated DC/DC Converters. The board’s digital interface can be read through the USB-I2C, which allows the user to receive power measurements and playback the data. It can also capture the time-varying waveform data, which allows developers to clearly visualize the system behavior.

The DC409A works by having an input voltage and an output voltage, from which it can detect and measure the resulting parameters. The board can read the voltage magnitude and current magnitude while automatically sensing the polarity of the current. The board reads the input voltage through an I2C-based analog multiplexer, while the output voltage is read through a Wheatstone bridge. This bridge then uses a mixed-signal ADCs which gives the user the power system performance data they require. Additionally, the DC409A also has two digital interfaces for communication, which grants the user full access to the graphical user interface.

When connected to a control system and configured, the DC409A can measure both the current limit and the minimum operating voltage. It can also measure power efficiency and standby power of the devices. The user can then input the target voltage, current limit, and shutdown voltage into the DC409A. Furthermore, the board incorporates multi-alarm outputs, which allows the user to set different power usage thresholds. Additionally, the DC409A operates at a frequency up to 10 kHz, which offers high-frequency functionality during the evaluation.

Overall, the DC409A offers a comprehensive set of features that enable developers to accurately measure any application’s power performance. The board is highly accurate, and its ability to interact with other external components makes it an ideal choice for device developers to test their system in one platform. The USB-I2C interface provides access to all the necessary parameters and application data, and its Wheatstone bridge and multi-alarm outputs offer flexibility and convenience. The DC409A is a great tool for device developers when it comes to evaluating their power systems.
