TLC5911 16 通道 LED 驱动器
TLC5911 描述
The TLC5911 is a constant current driver incorporating shift register, data latch, and constant current circuitry with a current value adjustable, PLL circuitry for gray scale control clock generation, and 1024 gray scale display using pulse width control. The output current is maximum 80 mA with 16 bits, and the current value of constant current output can be set by one external resistor. The device has two channel I/O ports. The brightness deviation between LED modules (ICs) can be adjusted by external data input from the display data port, and the brightness control for the panel can be accomplished by the brightness adjustment circuitry. Independent of these functions, the device incorporates the shift register and data latch to correct the deviation between LEDs by adjusting the output current using data from the dot correction data port.
