Overview
The TLC5927QPWPRQ1 is an automotive-grade 16-bit constant-current LED sink driver produced by Texas Instruments. This device is designed to provide uniform and constant current to LEDs, making it ideal for various LED display applications. It features a 16-bit shift register and data latches that convert serial input data into parallel output format, enabling the control of 16 regulated-current ports. The output current can be adjusted from 5 mA to 120 mA using an external resistor, offering flexibility in controlling LED light intensity. The device operates with a supply voltage of 3.3 V or 5 V and supports a high clock frequency of 30 MHz, suitable for high-volume data transmission.
