TLC5955RTQR is a type of PMIC (Power Management ICs), specifically a LED Driver. It is an integrated switch-mode power supply and current driver IC for driving an array of LEDs. The TLC5955RTQR provides a regulated and constant current output to the LEDs and allows the user to program the output according to their needs.

This integrated circuit is designed with a controlled-temperature and frequency conversion that help to reduce heat generation and also helps to make the IC more efficient. The TLC5955RTQR is integrated with two switching power stages, a smart-boost technique, low-side current source, temperature monitoring and over-temperature protection which helps the user to program the output of the LEDs efficiently. It is specifically designed to reduce audible noise and to ensure the LEDs remain cool.

The TLC5955RTQR has a wide input voltage range ( 2.5V to 72V ) and is capable of driving large numbers of LEDs. This IC has been tested and designed to drive arrays of up to 120 LEDs safely and efficiently. It is capable of simultaneously driving both low-power 50mA and high-power 350mA LEDs or the combination of both.

The TLC5955RTQR is used in a range of applications such as LED lighting, automotive interior/exterior lighting, medical lighting, and industrial lighting. The integrated high-brightness LED driver enables efficient LED drive and current control, LED dimming and protection from thermal overload. The LED brightness output can be changed through a PWM control or via external resistors. The IC is also capable of monitoring current output and voltages across the LED array.

The TLC5955RTQR is a highly efficient driver IC and is capable of achieving up to 97% energy conversion efficiency. The integrated, low-side current source makes the IC a very linearly controlled LED driver for both low and high current LEDs and guarantees that the LEDs are driven with a constant current. Furthermore, the integrated temperature monitoring and over-temperature protection functions ensure safe operation and provide LED driver protection against over-temperature faults.

The TLC5955RTQR is a reliable and highly efficient LED driver. It is designed with a low heat dissipation mode and its wide input voltage range makes it suitable for a wide range of applications. With its advanced features and functions, the TLC5955RTQR is ideal for driving an array of LEDs safely and efficiently.
