The TPS65197BRUYT is a very versatile, ultra-low power LED controller designed for portable displays. It is developed for low power applications such as mobile phones, portable video players, and tablet PCs.

The chip can control up to four channels of LEDs or two channels of RGB LEDs for video or graphics processing. The integrated voltage regulator provides a stable output voltage to drive the LEDs. With an ultra-low quiescent current, the TPS65197BRUYT is perfect for applications where power conservation is critical.

At the application level, the TPS65197BRUYT is a perfect fit for video processing. With its integrated capacitive color sensor and integrated color correction algorithms, it can accurately capture and process color data. The chip can also be used as a local display driver, allowing users to view high-quality digital videos and pictures without having to connect to an external monitor. This makes it ideal for environments where portability is key, such as a camping site or a school lab.

On the working principle level, the TPS65197BRUYT utilizes a simple two-wire serial interface for communication with a controller. This two-wire serial data bus can provide information regarding the colors of outputs, the input and output durations, and any timing commands from the main controller.

The TPS65197BRUYT provides four upstream and two downstream LED channels, capable of driving up to four colors (red, green, blue, and white) with a power consumption as low as 16 mW. The integrated voltage regulator can source or sink up to 25 mA for each LED channel, and the chip can automatically adjust its output levels to match the display luminance.

The chip is equipped with a tone-mapping algorithm that can automatically adjust the LED color brightness, enabling users to view videos with natural colors and high contrast. The integrated image sensor can identify colors, and the tone-mapping algorithm can adjust the LED output to mimic the exact brightness of the object. This feature helps to improve the image quality and reduce power consumption.

In addition to the integrated digital control, the TPS65197BRUYT also offer analog controls, allowing users to adjust the contrast and brightness of the display. This can be used to further enhance the video or graphic content for a better viewing experience.

The TPS65197BRUYT is an excellent LED controller for video or graphic processing applications. Its integrated features enable users to conveniently adjust the image brightness and color, while maintaining a very low power consumption. With its excellent performance, it is the perfect solution for portable displays.
