TLC5973D +BOM

TLC5973D is an ideal choice for high-speed LED lighting systems

TLC5973D General Description

The TLC5973D LED driver is a versatile and efficient solution for controlling LED displays with ease. With its 3-channel capability and 50-mA constant sink current, this driver offers a reliable way to power your lighting setup. The integrated 12-bit PWM resolution ensures smooth and precise control over the brightness of your LEDs, while the 3-Mbps serial interface simplifies the wiring process, reducing overall costs. Additionally, the driver's 2.9 kHz display repeat rate and 12-MHz grayscale clock oscillator provide a high level of performance for your LED applications
