The TLC592x is designed for LED displays and LED lighting applications with open-load, shorted-load, and over temperature detection, and constant-current control. The TLC592x 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 mA to 120 mA through an external resistor, Rext, which gives flexibility in controlling the light intensity of LEDs. The TLC592x is designed for up to 17 V at the output port. The high clock frequency, 30 MHz, also satisfies the system requirements of high-volume data transmission.
