Mini-LED TV Backlight Unit - Large Matrix

The real-time Arm^® Cortex^®-R4-based MPU enables control of a large matrix LED backlighting system for state-of-the-art TVs, paired with our high-precision 32-channel LED backlight driver. The integrated driver feedback channel dynamically minimizes overall power consumption by controlling the LED supply voltage level. The digital system and interface power are provided by a processor power management IC (PMIC) and a high-efficiency buck converter. The QSPI flash memory stores software and brightness mapping, while temperature sensors optimize performance under varying conditions.

System Benefits​:

• Flexible MPU-based, software-controlled, large matrix luminance and chrominance control.
• The MPU minimizes propagation delay between LED adjustment and video content, reducing the video buffer size.
• Dynamic LED supply voltage adjustment minimizes power loss.
• Highly integrated and efficient system PMIC.
• Single variable voltage rail from LLC to power LEDs and system power.
• Temperature sensor to optimize system performance.
