The LX1990-02 EVAL KIT is a complete evaluation platform developed and distributed by Lattice Semiconductor Corporation. It is designed to evaluate motor control, communication and LED mixing solutions. It is an ideal platform for designers of all levels to quickly develop and customize a complete system that meets their specific lighting needs.

The LX1990-02 EVAL KIT consists of the LX1990 LED Drive IC, various Lattice devices, a timer, a display, a light sensor and other components. The LX1990 LED Drive IC has built in real-time clock, on/off switches, digital PWM and a three-way hue adjustment feature which can be used to create a variety of lighting effects. The IC also provides an adjustable dimming function with both time-based and level-based dimming capabilities. The kit also includes an onboard light sensing device which can detect incoming light levels and adjust the LED output accordingly.

The LX1990-02 EVAL KIT application field relates to LED drivers and is used to evaluate TFT monitors, display backlighting, and backlight illumination. It is also used to measure current, voltage and power at the input and output nodes, including higher voltage drivers and dimmable LED drivers according to the application requirements. In additional, the EVAL KIT can also be used to evaluate video and audio signal accuracy.

The basic working principle of the LX1990-02 EVAL KIT starts with the choice of the pins of the LED driver IC. Depending on the application, the pins need to be chosen such as PWM, DI and DO, I2C etc. Then these pins need to be connected with different parts of the board or any other external components depending on the type of solution being tested. After this connection is done, the code needs to be written to control the pins for exerting different effects on the LED driver IC based on the application. For example, if the application belongs to a dimmable LED driver, then the PWM pin has to be programmed in such a way that the LED output can be varied with different dimming levels. Similarly, if the application belongs to display backlighting or backlight illumination, then the pins have to be programmed in such a way that the LED output has the desired brightness, color and other effects.

In conclusion, the LX1990-02 EVAL KIT falls into the category of Evaluation Boards - LED Drivers and provides an ideal evaluation platform for designers to develop and customize a complete system that meets their specific lighting needs. It permits various LEDs to be interfaced together to create dynamic light effects and can be used to measure current, voltage and power at the input and output nodes. It also allows video and audio signal accuracy to be evaluated. All of these features combine to make the EVAL KIT an incredibly versatile device for testing different types of LED based applications.
