Evaluation Boards: LED Drivers

LM3590MFEV Application Field and Working Principle

The LM3590MFEV Evaluation Board is a DC/DC converter that operates with an output current of up to 5A, powering LED lighting and general LED controls. This evaluation board is manufactured by Texas Instruments and is designed for LED drivers and is commonly used for LED dimming, LED string protection and LED functional testing.

Features and Benefits

This evaluation board offers the high efficiency design found in Texas Instruments Switch Mode Power Supply products. Some of the details that make the LM3590MFEV board beneficial to applications are its low power and low current constraints, potential for wide operating temperature ranges, high accuracy temperature compensation, excellent thermal protection and high efficiency synchronous rectification.

Operation

The LM3590MFEV Evaluation Board operates on between 7v to 28v. It will recognize and detect current automatically when a load is present. The board has two principle components, which are the I2C interface used to control the external LED’s, and the power stage, which is comprised of the power IC, controller and MOSFETs. The power stage has a voltage mode control for best power benefits and less emissions.The board is designed with a bright LED indication for when the board is powered and enabled. The device is identified by an address that can be set by the I2C interface. The board will automatically detect an over-current condition and shut off the load to protect against damages.

Applications

The LM3590MFEV Evaluation Board is commonly used for different applications related to LED lighting. This includes general lighting and display lighting, automotive lighting, architectural lighting and home equipment and accessories.The board can be connected as a parallel or series power stage depending on the application and can be used to update existing systems or develop alternatives in existing designs. In addition, the board allows for consistent brightness, independent dimming control, improved power draw and support of much higher current rating systems.

Conclusion

The LM3590MFEV Evaluation Board is a valuable tool for lighting applications. It includes a high efficiency design and offers low power constraints, wide operating temperature ranges, high accuracy temperature compensation and excellent thermal protection. The board is also capable of series and parallel configurations, independent dimming control and auto-detect over-current conditions. With its inherent features, the board is capable of offering brilliant performance to a wide array of LED lighting projects.
