TLC5925 - Texas Instruments

TLC5925 Low-Power 16-Channel Constant-Current LED Sink Driver

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 d.
