TITLC5947DAP
Overview
The TLC5947DAP is a 24-channel constant-current sink LED driver featuring integrated 12-bit PWM grayscale control for every channel. It operates via a simple serial interface and includes an internal 4MHz oscillator, allowing it to manage complex LED dimming independently of continuous MCU timing signals.
Why Choose This Part
The device simplifies high-density LED designs by integrating 24 channels into a single 32-HTSSOP package with thermal shutdown protection. Its grouped 4-channel delay architecture effectively reduces inrush current and switching noise during PWM cycles.

Getting Started
To evaluate this IC, look for the TLC5947EVM-433 evaluation module which provides a pre-assembled platform for testing the 30mA sink outputs. Communication is handled via a standard 4-wire serial interface (SIN, SCLK, XLAT, SOUT), allowing multiple units to be easily cascaded.
