The TLC5925IDWR is a Low-power 16-channel Constant Current LED Sink Driver designed for LED displays and LED lighting applications. It 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 3mA to 45mA through an external resistor, Rext, which gives flexibility in controlling the light intensity of LEDs. TLC5925 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. The serial data is transferred into TLC5925 via SDI, shifted in the shift register and transferred out via SDO.
