LED drivers are a type of electronic device designed to convert electrical power into light. They are commonly used in automotive lighting, medical devices, headlights, traffic signals, and home and office lighting applications. The LX1990-03W EVAL is a high-efficiency, high-power LED driver evaluation board designed to meet the needs of automotive lighting application environments.

The LX1990-03W EVAL board is based on the LM35601 high-efficiency, high-power LED driver from Texas Instruments. It is a switch-mode power supply that is capable of driving up to 4 LEDs at a maximum output current of 1A per channel. The board integrates a low-noise switching regulator and an adaptive FT frequency control to reduce electromagnetic interference. In addition, it has a wide input voltage range of 4.4V to 40V, allowing it to be used in a wide range of automotive lighting applications.

The LX1990-03W EVAL board is a high-efficiency LED driver that improves light output efficiency compared to traditional LED drivers. It utilizes an adaptive frequency-corrected synchronous rectification (AFCC) protocol, along with a sophisticated power control management algorithm, to deliver higher efficiency in the given input voltage range. This improves the conversion efficiency of the driver to up to 94%. The low operating temperature of the LX1990-03W EVAL ensures a longer product life for automotive lighting applications.

In addition, the LX1990-03W EVAL has integrated over-voltage and over-current protection circuits to protect the LEDs from damage. It also has a built-in dynamic low-current control function to reduce power consumption during light-load status. This helps to further improve the overall efficiency of the driver. The LX1990-03W EVAL board also comes with an on-board temperature sensor and over-temperature protection circuit to protect the LEDs from damage due to excessive temperature.

The application field of the LX1990-03W EVAL is mainly aiming at automotive lighting applications. It is suitable for applications such as daytime running lights, fog lights, and tail lights. The board is designed to be compatible with LED strips and LED modules and can drive up to 4 LEDs in parallel. The board is also compatible with 12V automotive electrical systems, making it an ideal choice for automotive lighting applications.

In conclusion, the LX1990-03W EVAL is a high-efficiency, high-power LED driver evaluation board designed for automotive lighting applications. It has a wide input voltage range and can drive up to 4 LEDs in parallel. In addition, it has integrated over-voltage and over-current protection circuits, along with a built-in dynamic low-current control function for improved efficiency. It is also compatible with LED strips and LED modules and is suitable for automotive lighting applications such as daytime running lights, fog lights, and tail lights.
