The working principle behind the TLC5957RTQT LED driver is based on the buck-boost current mode pulse width modulation (PWM) architecture. In this configuration, the current capability of the LED driver is increased by using a high-efficiency buck-boost switching regulator with a regulated switch waveform to adjust the amount of current going to the LEDs. When the output voltage of the LED driver is low, the buck-boost switching regulator boosts the current, while when the output voltage of the LED driver is high, the switching regulator buck the current. This switching architecture enables the operating efficiency to remain high, and the temperature rise to remain low.

Additionally, the TLC5957RTQT LED driver features an adjustable system frequency range from 2.5kHz to 32kHz, which allows for flexibility and improved system design. This makes it suitable for applications such as LED lighting and display systems, providing a wide range of output voltage and current levels for improved performance and reliability.
