TITLC5947
Overview
The Texas Instruments TLC5947 is a 24-channel constant-current LED driver designed for applications requiring precise control of multiple LEDs. It features 12-bit PWM grayscale control for smooth dimming and a 30-MHz data transfer rate.
Why Choose This Part
This LED driver offers 24 constant-current sink outputs, each capable of 30 mA, allowing for a large number of LEDs to be driven from a single IC. The 12-bit PWM grayscale control provides fine resolution for dimming. Its internal 4-MHz oscillator simplifies design, and features like thermal shutdown and noise reduction enhance reliability.
