Programmable 4-ch LIN RGB Driver The TLD4020-4ET is a 4-channel linear LED driver with integrated MCU application platform. It is designed for automotive interior ambient lighting to drive one RGBW LED or two white LEDs up to 64.0625 mA as linear current sink (LCS). It enables pure RGB and tunable white with state-of-the-art color accuracy, smooth color transitions, and dimming. The device integrates a 32-bit Arm® Cortex®-M23 core, 32 kB on-board flash, and an 11-bit ADC.
