The TLC5949PWP is an LED driver produced by Texas Instruments, which applies to LED display, LED lighting and LED mobile lighting. This LED driver is an 8-channel serial-in/serial-out shift register, providing constant current at up to 44V output. Each of the 8 channels can be enabled or turned off, and 8 LEDs can be connected in series to obtain higher output voltage. The maximum recommended output current of each channel is 50mA. Each register\'s output includes a pass transistor for capacitively coupled PWM control.

TLC5949PWP is available in two packages, either a TSSOP-16 or a VQFN-20 package. The applications for this LED Driver include world and indoor home lighting applications, as well as LCD backlight displays and scrolling marquees. Its user-friendly interface allows it to be easily integrated into a wide variety of designs.

The TLC5949PWP is designed with an ultra-low operating voltage range of 1.8V to 5.5V, with an output current range of 25mA to 100mA per channel. Output current regulation is achieved through the use of an adjustable current sink and an adjustable voltage source. Additionally, the output current can be set by adjusting the current source and sink. The current source and sink are adjustable through a common control line.

Users may choose to control the LEDs through the serial interface shift register, or through I2C/I2S, PWM or analog-controlled DAC outputs. The TLC5949PWP is capable of achieving a high switching frequency of 80MHz, offering fast response times and flexibility. Its wide voltage range is ideal for low-power applications, allowing it to save power when operating at high output current levels.

The TLC5949PWP is an efficient LED driver that provides excellent LED current accuracy and high LED life expectancy. In addition, it includes built-in protection features, such as over-temperature, over-voltage, and over-current protection. These built-in protection ensures safe and efficient operation, providing a safe and reliable LED driver in any illumination application.

The TLC5949PWP is a high-performance LED driver that offers a wide variety of features and flexibility to the user. It offers excellent LED current accuracy, low operating voltage, and high switching frequency. Its wide voltage range and adjustable current sink and voltage source make it a perfect choice for low-power applications, while its integrated protection features ensure safe and reliable operation.
