The TLC5973 is an easy-to-use, 3-channel, 50-mA constant sink current LED driver. The single-wire, 3-Mbps serial interface (EasySet) provides a solution for minimizing wiring cost. The LED driver provides 12-bit pulse width modulation (PWM) resolution. The display repeat rate is achieved at 2.9 kHz (typ) with an integrated 12-MHz grayscale (GS) clock oscillator. The driver also provides unlimited cascading capability.

All output sink constant currents can be set by an external resistor. The TLC5973 has an internal shunt regulator that can be used for higher VCC power-supply voltage applications.
