The TPS61180RTER is a high-voltage, high-current, high-power LED driver with step-down DC-DC converter capability. It is a PMIC (Power Management IC) that offers advanced features like pulse-speed dimming (PSD) and temperature-compensated buck regulator (TCB) operation. It is mainly used in LED backlighting systems in mobile, industrial, and automotive applications.

The TPS61180RTER is a low-voltage buck driver with a step-down topology. It is capable of providing a constant, regulated voltage to an LED load, even when the input voltage can vary between 3V and 28V. The output voltage is adjustable from 0.4V to 20V, perfect for LED modules. The buck regulator also features an overvoltage protection of up to 30V, providing a reliable power supply to the LED modules.

The high-efficiency TPS61180RTER operates at up to 97%. It has an integrated MOSFET which helps reduce power losses. It also supports pulse-speed dimming (PSD) through its PWM dimming pins allowing system designers to save power up to 30%. It also supports a low-voltage programmable current sense (VCS) pin, allowing the LED brightness to be controlled precisely.

The TPS61180RTER also includes a temperature-compensated buck (TCB) regulator, which helps ensure that the LED output remains consistent over a wide range of temperatures. The TCB also allows for a low start-up voltage, reducing the system impact on power supply voltage drops. It also supports an integrated fault-detection circuit to provide short-circuit, open-wire and over-temperature protection. This helps to ensure a safe and reliable operation of the LED.

The TPS61180RTER is designed to operate in low-noise, low-reflection environments with frequencies up to 2.4MHz. It is available in a 20-pin TSSOP package, making it ideal for space-saving applications. It also features an over-temperature protection for extra safety, as well as an integrated power-on reset circuit.

To sum up, the TPS61180RTER is a high-voltage, high-current, high-power LED driver with step-down DC-DC converter capability. It offers advanced features like pulse-speed dimming and temperature-compensated buck (TCB) operation which allows it to provide a reliable and efficient power supply to the LED modules. It is mainly used in LED backlighting applications in mobile, industrial, and automotive applications.
