SLVS515D – DECEMBER 2004 – REVISED NOVEMBER 2015 TLC5940 16-Channel LED Driver With DOT Correction and Grayscale PWM Control
1 Features 3 Description •
•
• The TLC5940 is a 16-channel, constant-current sink
LED driver. Each channel has an individually
adjustable 4096-step grayscale PWM brightness
control and a 64-step, constant-current sink (dot
correction). The dot correction adjusts the brightness
variations between LED channels and other LED
drivers. The dot correction data is stored in an
integrated EEPROM. Both grayscale control and dot
correction are accessible through a serial interface. A
single external resistor sets the maximum current
value of all 16 channels. 1 • •
