The TLC5926IDBQR is a 16-channel constant-current LED Sink Driver for LED displays with open-load, shorted-load, over-temperature detection and constant-current control. It contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. At the TLC592x output stage, 16 regulated-current ports provide uniform and constant current for driving LEDs within a wide range of VF (forward voltage) variations. Used in systems designed for LED display applications (for example, LED panels), TLC592x provides great flexibility and device performance. Users can adjust the output current from 5 to 120mA through an external resistor, Rext, which gives flexibility in controlling the light intensity of LEDs. It is designed for up to 17V at the output port. The high clock frequency, 30MHz, also satisfies the system requirements of high-volume data transmission.
