RGB LED Cluster Lamp Displays
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.
Output sink current can be set by each external resistor connected to the OUTn terminal in series. The TLC59731 has an internal shunt regulator that can be used for higher VCC power-supply voltage applications.
