The TLC59025IDBQR is a 16-channel low-power constant-current LED Sink Driver designed for gaming machine/entertainment. It contains a 16-bit shift register and data latches, which convert serial input data into parallel output format. At the TLC59025 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 (for example, LED panels), it provides great flexibility and device performance. Users can adjust the output current from 3 to 45mA 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.
