Evaluation Boards – LED Drivers

Evaluation boards – LED drivers are devices that provide LED lighting for different applications. LED lighting has become popular over the years because of its efficiency and economical appeal. The ADM00641 evaluation boards from Texas Instruments are a perfect example of LED driver evaluation boards. In this article, the ADM00641 application field and working principle will be discussed.

ADM00641 Application Field

The ADM00641 is a high-speed LED driver board in a very small form factor. It has features such as wide input voltage range (from 4.5V to 25V), adjustable brightness and dimming, thermal protection, and a wide range of power modes for various applications. The board can be used for a variety of LED lighting applications, such as automotive lighting, medical lighting, industrial lighting, and general lighting.

Working Principle of ADM00641

The ADM00641 LED driver uses a combination of linear and switching regulator technologies. The input voltage is initially regulated by a linear regulator. The regulated voltage is then used to drive the main switching stage, which boosts the voltage and provides the necessary current to power the LED. The main switching regulator is based on DC-DC controller IC DM2652 that supports a wide range of input voltages. The board supports both constant current (CC) and constant voltage (CV) control modes. In CC mode, the output current is regulated by controlling the pulse width modulation duty cycle. In CV mode, the output voltage is regulated by controlling the duty cycle of the PWM signal.

The ADM00641 also features multiple protection features such as over temperature protection, over current protection, and under voltage lockout. These features ensure reliable operation at all times. In addition, the board comes with an integrated diagnostic LED that provides an indication of the board’s status and helps the user to troubleshoot any issues.

Conclusion

The ADM00641 evaluation board is a perfect choice for developing LED lighting solutions. The board is compact, cost-effective, and offers a very flexible design. The board also has plenty of protection features that ensure reliable and safe operation at all times. The versatility of the board makes it ideal for applications such as automotive lighting, medical lighting, industrial lighting, and general lighting.
