TLC59731DR Datasheet PDF - TI

●Description

●The TLC59731 device is an easy-to-use, 3-channel, 50-mA sink current LED driver. The single-wire, 600-kbps serial interface (EasySet) provides a solution for minimizing wiring cost. The LED driver provides 8-bit pulse width modulation (PWM) resolution and a simple gamma correction feature. The display repeat rate is achieved at 3.1 kHz (typical) with an integrated 6-MHz grayscale (GS) clock oscillator. The driver also provides unlimited cascading capability.
