EA8930 is an evaluation board designed by EA to evaluate the actual performance of the DC/DC and AC/DC (Off-Line) SMPS. It is a system with a self-contained power supply and a microcontroller-based peripheral interface to allow quick development and evaluation of the DC/DC and AC/DC SMPS platforms. The EA8930 evaluation board provides a high quality and reliable environment for testing and evaluation.

Application Field

The EA8930 is designed for use in evaluating DC/DC or AC/DC off-line power supplies. It can be used as an input to a current supply system, to convert the voltage and/or current supplied by an external source and convert it to the stable power needed by the equipment. The evaluation board can also be used to evaluate the performance and reliability of the power circuits used in a wide range of industrial, medical, and other applications.

Features

The EA8930 includes features such as digital control, comprehensive feedback control, comprehensive overload protection, non-destructive testing, and real-time monitoring. The board also includes a built-in microcontroller that allows for easy configuration anddebugging. The microcontroller includes a full-speed USB interface and RS-232 for communication. The EA8930 also supports a wide range of power configurations, including line-powered, dual-output, single-output, dual-rail, and multi-point systems.

Working Principle

The EA8930 is designed to be used in conjunction with an external power source. The board measures the input voltage and current from the external source and uses that information to regulate the output power of the system. It includes a voltage feedback loop to ensure that the voltage stays within the specified operating range. The EA8930 also includes an overload protection circuit, which will shut off the power if the output current exceeds the specified limit. The board also includes a temperature monitor that will shut off the power if temperatures exceed a certain level.

The EA8930 is designed with a firmware-controlled Microcontroller and a digital switching controller, which is used to regulate the output of the power supply. The Digital switching controller reads the input voltage and current from the external source and calculates the optimum output voltage and current. The digital switching controller then passes on the information to the Microcontroller, which then makes the required changes in the power supply output. The Microcontroller also monitors the output current and triggers the overload protection circuit if required.

The EA8930 evaluation board provides a wide range of features and capabilities, making it an ideal platform for evaluating DC/DC and AC/DC (Off-Line) power supplies. It is designed for use in any application requiring reliable, stable power, and can easily be integrated into existing or new designs.
