TLC59731DR

LED照明驱动器 3-Ch 8B PWM LED Dvr

Description

The TLC59731 device is an easy-to-use, 3-channel, 50-mA sink current 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.
