The TLC69634-Q1 is a LED driver with 24 constant current sink channels which can provide up to 16-bit individual pixel-level LED PWM control. The additional 7-bit dot correction (DC) is also implemented to each channel to control peak current. Each device shares data stream by serial peripheral interface (SPI) which supports up to 511 devices connection. The interface is software compatible with LED drivers in the same group which can be applied to different application scenarios based on LED current and total LED number.

To optimize overall systematic power efficiency, the device is equipped with adaptive headroom voltage control (AHVC) scheme to optimize headroom voltage across each channel and device. Only the OUT23 pin from the last device of daisy chain is required to be programmed as FB pin to optimize LED supply voltage from DC/DC.

The TLC69634-Q1 is equipped diagnostics for LED, current sink, communication and device.
