The TPS61160DRVRG4 is a PMIC (Power Management IC) LED driver, which is specifically designed for energy-efficient LED drives for displays of mobile applications. It provides a high efficiency solution that helps to reduce power consumption and extend battery life in smartphones and tablets. The TPS61160DRVRG4 can operate in both PWM (pulse-width modulation) mode and analog dimming mode, which allows for precise control of the LED drive current and brightness. The TPS61160DRVRG4 also features short-circuit protection, overload protection, and thermal shutdown.

The TPS61160DRVRG4 is designed in a 1.6mm x 2mm x 0.55mm package and integrates several functions in one chip, including a switching regulator, PWM dimming control, LED flexible current sensing control, LED open/short protection, LED reverse protection, and 200°C thermal shutdown. The switching regulator provides adjustable output voltage (2.5V to 6.3V) and a constant output current of up to 20mA. The PWM dimming control allows for smooth dimming with 0~100% duty cycle and frequencies up to 20kHz. The LED current sensing control adjusts the LED current (8.2-24 mA) based on the input voltage, so the brightness of the LED will be the same regardless of the voltage. The LED open/short protection instead, protects the LED from damages due to open or short circuit events. The reverse protection ensures that the current does not flow back from the LED when the power is off.

The TPS61160DRVRG4 is a great choice for energy-efficient LED displays of mobile applications, as it helps to extend battery life and reduce power consumption. It is designed to provide both PWM and analog dimming and allows for precise control of the LED drive current and brightness. Additionally, it features open/short protection, reverse protection, and thermal shutdown.
