SLVS765B – OCTOBER 2008 – REVISED SEPTEMBER 2015 TLC5925 Low-Power 16-Channel Constant-Current LED Sink Driver
1 Features 3 Description The TLC5925 is designed for LED displays and LED
lighting applications. The TLC5925 contains a 16-bit
shift register and data latches, which convert serial
input data into parallel output format. At the TLC5925
output stage, 16 regulated-current ports provide
uniform and constant current for driving LEDs within a
wide range of VF variations. Used in system design
for LED display applications (such as, LED panels),
the TLC5925 provides great flexibility and device
performance. Users can adjust the output current
from 3 mA to 45 mA through an external resistor,
Rext, which gives flexibility in controlling the light
intensity of LEDs. TLC5925 is designed for up to
17 V at the output port. The high clock frequency, 30
MHz, also satisfies the system requirements of highvolume data transmission. 1 16 Constant-Current Output Channels
