explain
TLC59731 device is an easy to use 3-channel 50mA perfusion LED driver. This single wire, 600kbps serial interface (EasySet) provides a solution that greatly reduces the cost of wiring. The LED driver provides 8-bit pulse width modulation (PWM) resolution and a simple gamma correction feature. The device is integrated with a 6MHz gray scale (GS) clock oscillator, which can make the display repetition rate reach 3.1kHz (typical value). This drive also provides unrestricted cascading capabilities.
