TPS92518PWPR

A PMIC LED Driver is an integrated circuit for managing LED lights with high accuracy. The joules, volts, and current are controlled to power the lights in a safe and efficient manner. The TPS92518PWPR is a PMIC LED Driver series made by Texas instruments.

The TPS92518 is a high-performance, flexible LED driver intended for interior car lighting and suitable for driving up to four 11mA LEDs or one 33mA LED in series. It uses a buck topology and allows adjustable forwarding currents up to 33mA and a forward voltage up to 45V. The output current is set by adjusting the external resistor, which is connected to the voltage reference block (VRB) of the integrated circuit. The VRB provides an accurate reference voltage, which ensures a tight current regulation and eliminates the need for current sensing.

The TPS92518 is designed to operate in a wide range of operating temperatures from -40°C to 125°C and also offers protection from output shorts and battery over-voltage. The device utilizes built-in soft-start for increased system efficiency and safety. Its low quiescent current of 10µA helps extends battery life.

Applications for the TPS92518 include interior automotive lighting, projection lamps, and decorative lighting. This PMIC LED driver is well-suited for a variety of applications due to its high efficiency, compact size and features.

In conclusion, the TPS92518PWPR is an efficient and versatile PMIC LED driver series. It offers protection from output short-circuits and battery over-voltage and provides a high level of accuracy when controlling LED lights. This driver is suitable for a variety of applications, such as interior car lighting, projection lamps, and decorative lighting. The device also offers a wide range of operating temperatures and low quiescent current to extend battery life.
