Evaluation Boards - LED Drivers

VIPER22-LED-EV are LED drivers evaluation boards that provide the ability to evaluate the advantages of a Wide Range OFF-Line LED Driver.

Application field

VIPER22-LED-EV are suitable for LED lighting applications where efficiency, low cost, high power, and low power consumption are required. In addition, these boards are ideal for applications where reliable operation is a critical factor such as traffic lights, chaser lighting, and illustrated panels. The boards are suitable for use in a variety of application fields, including automotive, industrial, commercial and residential environments.

Working principle

VIPER22-LED-EV LED drivers have a working principle that is easy to understand. The board operates as follows; a high frequency AC line voltage is applied to the primary side of an isolation transformer, and the secondary winding is connected to the VIPER family of ICs. The IC senses the supply voltage, adjusts its operation to the most appropriate frequency, and provides the appropriate current to the LEDs. The ICs in the VIPER22-LED-EV are programmable and can be adjusted via their serial bus. It is also possible to adjust the driver output current to create an optimal amount of light output. Additionally, the ICs can be set to provide constant current output or be programmed for use in switching applications such as light dimmers for smart homes. The ICs on the VIPER22-LED-EV are equipped with LEDs to indicate the board’s operational status and also provide extra brightness to a system if required. Furthermore, to ensure long service life, the VIPER22-LED-EV is designed for a maximum junction temperature of 125°C.

Conclusion

The VIPER22-LED-EV evaluation boards provide an easy to use and cost effective solution for evaluating a wide range of LED lighting applications. Their programmable ICs allow for efficient and reliable operation while also providing additional features such as status LEDs and dimming capabilities. By using the VIPER22-LED-EV evaluation boards, designers can evaluate the efficiency, cost and performance of the LED lighting applications they are designing and ensure that they are appropriate for their application requirements.
