Overview

The TLC59711PWPR is a 12-channel, constant-current sink LED driver featuring 16-bit enhanced spectrum PWM grayscale control and an integrated 3.3V linear regulator. It supports a wide output voltage range up to 17V and includes global brightness control, making it ideal for high-precision RGB and video display applications.

Why Choose This Part

It offers superior 16-bit grayscale resolution compared to standard 8-bit drivers, alongside an internal watchdog timer for safety and a 3.3V LDO to power external circuitry. The constant-current sink architecture ensures uniform LED brightness across all 12 channels even with supply fluctuations.

Applications

RGB LED Clusters
Precise 16-bit PWM control for each channel allows for smooth color mixing and high-resolution dimming in decorative lighting.
Video Displays
Enhanced spectrum PWM reduces flicker, while the 10MHz clock frequency supports high-speed data cascading for large LED walls.
Backlighting
Used in LCD panels and instrumentation where uniform brightness and high-dynamic-range dimming are required.

Getting Started

Connect the device via a simple two-wire serial interface (Data and Clock) to any MCU. Use the 3.3V VREG output to power your logic if needed, and ensure the thermal pad is soldered to a ground plane for heat dissipation at high current loads.

Also Consider

TLC5940PWPR TITexas Instruments - Offers 16 channels instead of 12 for higher density, though with 12-bit PWM resolution.
PCA9685 NXP Semiconductors - A 16-channel alternative using an I2C interface instead of a high-speed shift register, suitable for lower-speed requirements.
