description
The TLC5920 is an LED driver incorporating a
16-channel shift register, data latch, and constant
current circuitry with current value control and
8-channel common driver into a single chip. The
constant output current is capable of 30 mA for 16
bits simultaneously, and the current value can be
set by one external register. This device also
includes a 16-bit segment driver and 8-bit
common driver; therefore, the monocolor LED
array with 16 × 8 dots can be driven by only one
TLC5920, and a two-color LED array with 16 x 16
dots can be driven by two TLC5920s.
