This article provides an overview of the application field and working principle of the AS3694 demo board assessment boards, which are used as LED drivers. It begins with a brief overview of the purpose of the AS3694 evaluation boards, followed by a detailed explanation of the various features and components of the boards. It then explores the application field and working principle of the demo board in greater depth.

Overview of AS3694 Evaluation Boards

The AS3694 evaluation boards, also known as LED drivers, are used to test, evaluate and debug LED applications. An LED sample of the LED technology used for the application is connected to the board to assess LED performance. Evaluation boards provide accurate testing and evaluation results that help guide engineers in creating LED designs. The board consists of a high power LED and a power supply, along with a range of features such as a temperature sensor, display, dimming and data acquisition.

Features of the Evaluation Boards

The AS3694 evaluation boards offer numerous features to allow for accurate testing and evaluation of LED applications. One of the key features of the boards is the built-in temperature sensor which helps to monitor temperature conditions and protect LEDs from becoming too hot. The temperature condition can then be observed and adjusted as necessary. Other features of the board include a display, dimming, voltage and PWM output modes, and robust data acquisition systems.

Application Area of the Demo Board

The AS3694 demo board is suitable for a wide range of applications, including automotive headlight, tail light and dashboard application, architectural lighting, industrial lighting, and medical lighting. Specific applications may require further customisation to meet specific application requirements.

Working Principle of the Demo Board

The AS3694 demo board uses a simple and efficient working principle. The board consists of a power supply, a high power LED, a temperature sensor, and control features such as a display and dimming. In use, the LED is connected to the board and powered up, and the sensor measures the temperature of the LED. The control features are then used to adjust the LED’s performance, e.g. to dim the LED or change the brightness, according to the requirements of the application.

Conclusion

The AS3694 evaluation boards are LED drivers that are used to evaluate LED performance. They feature a range of components and control features, and are suitable for a range of applications including automotive and medical lighting. The boards use a simple but effective working principle to assess LED performance, consisting of a power supply, a high power LED, a temperature sensor, and control features such as a display and dimming.
